I saw a lot or request about rich link preview in Telegram, but this is specifically about "how to get a BIG/LARGE image" in the preview.
Let's take this article on my site as example. It already has all of the OGs:
<meta property="og:title" content="Questa settimana su TLI (08 dicembre 2018)" />
<meta property="og:type" content="article" />
<meta property="og:image" content="https://turbolab.it/immagini/12483/max" />
<meta property="og:url" content="https://turbolab.it/newsletter-turbolab.it-1349/questa-settimana-tli-08-dicembre-2018-1812" />
<meta property="og:description" content="Non hai tempo di leggerci tutti i giorni? nessun problema! ecco a te il riepilogo di quanto proposto da TurboLab.it nel corso della settimana in conclusione." />
<meta property="og:locale" content="it_IT" />
<meta property="og:site_name" content="turbolab.it" />
Result: it works when the link is posted on Telegram, but the image is small and floated right even if the og:image (this) is 1000 px wide. I'd like to have it big, on it's own line.
Check this out (first entry is my site, the one I want to fix: note the small image, floated right. 2nd and 3rd is the result I want as shown by a YouTube video and a Mashable article).
The 3 URLs used in the image above are:
https://turbolab.it/newsletter-turbolab.it-1349/questa-settimana-tli-08-dicembre-2018-1812
https://www.youtube.com/watch?v=y6eHY537Cao
https://mashable.com/article/xiaomi-48-megapixel-camera/?europe=true&utm_cid=hp-r-1#cR2kG7X_naqO
richpreview.com isn't helpful, because it preview the image as "small" on all of the theree (one, two, three).
Strange thing is: it works as expected on Facebook. There, I get big, wide images. It's perfect on Twitter too.
What am I missing?
Adding twitter meta tags fixed the issue for me
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:image" content="{IMAGE URL}" />
Telegram bases its preview images on Twitter sharing cards markup. You're missing the summary_large_image content. You need to add the following in addition to what you have:
<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:image" content="https://turbolab.it/immagini/12483/max">
Once you've updated your markup, paste the share link in to Telegram's Webpage Bot and choose Update Preview to clear Telegram's image cache and view the enlarged image.
Consult Summary Card with Large Image on Twitter Developers for more info.
To further enrich your results with large images you could also create a Telegram Instant View. Note however Instant Views only appear for designated templates chosen by Telegram itself.
Example custom Instant View Template:
# enable for items in the post section
?path: /post/.+
# define required elements
title: //*[#itemprop="headline"]
body: //*[#itemprop="articleBody"]
# if cover exists, define images
?exists: //head/meta[#property="og:image"]/#content
cover: //head/meta[#property="og:image"]/#content
image_url: $cover/self::img/#src
Example meta tag for to allow joins to your channel from the Instant View:
<meta property="telegram_channel" content="turbolabit">
You may lose some visibility of your visitor metrics but your users will have a better experience reading and enjoying your site from within Telegram which translates into brand recognition.
You're missing the Open Graph protocol prefix-attribute in your html tag:
<html prefix="og: http://ogp.me/ns#">
Learn more about the Open Graph protocol at ogp.me.
here is the image
anyone know? what's the problem
here are the tags i m using in html.
<meta property="og:type" content="product" />
<meta property="og:title" content="Deft Multi-concept Coming Soon Template" />
<meta property="og:description" content=" build you online presense righ now with a beautiful coming soon tempalte." />
<meta property="og:url" content="http://www.coderare.com/deft-coming-soon-template.html"/>
<meta property="og:site_name" content="Coderare" />
<meta property="og:price:amount" content="12.00" />
<meta property="og:price:currency" content="USD" />
<meta property="og:availability" content="instock" />
<meta property="og:image" content="http://www.coderare.com/img/5.png" />
and when ever i'm tring to validate my page it shows "Something went wrong on our end" what's that?
According to the pinterest documentation the product tags you have used are not the ones pinterest supports. Instead use product:price:amount product:price:currency
You might also want to include structured data from http://schema.org for information not included in the pinterest product tags, eg In Stock.
Stackoverflow's help section has further information on debugging steps that will help you narrow down problems to the exact lines that cause the errors.
When I shared a link on the Facebook, Facebook only show the last or previous of my Website.
New title: Kirk Niverba | Official Website
Old Title: W3Schools Web Development
Picture Titles | Facebook
Note that in the "New Title" is scriptly edited on Facebook (Inspect Element edit)
Thanks for someone will notice this =)
I think i understand. In order for you to do this, look specifically at this link
https://developers.facebook.com/docs/plugins/like-button
Which gives you some ideas about how to specify the content shown on Facebook once someone shares your web page, on their FB page.
Also for some added reference, check this links as well.
https://developers.facebook.com/docs/sharing/web
It will give you what you need.
EDIT*** specifically, when you add it properly, these lines will give you exactly what you need alongside an image for your post/share.
<head>
<title>Your Website Title</title>
<!-- You can use open graph tags to customize link previews.
Learn more: https://developers.facebook.com/docs/sharing/webmasters -->
<meta property="og:url" content="http://www.your-domain.com/your-page.html" />
<meta property="og:type" content="website" />
<meta property="og:title" content="Your Website Title" />
<meta property="og:description" content="Your description" />
<meta property="og:image" content="http://www.your-domain.com/path/image.jpg" />
</head>
Otherwise, FB uses old/current page data at random i believe. Or based on a percentage of the top 1/3 of the page(if i remember correctly).
THE PROBLEM:
I am trying, without much success, to implement open graph image on site: http://www.guarenty-group.com/cz/
The homepage is completeply bypassing the og:image tag, where internal pages are reading all images from the site and place og:image as the last option.
Other social networks are working fine on both internal pages and homepage.
THE CONFIGURATION:
I have no share buttons or alike, all I want is to be able to share the link via my profile.
The image is well over 300x300px: http://guarenty-group.com/img/gg_seal.png
Here is how my head tag looks like:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Guarenty Group : Pojištění pro nájemce a pronajímatelé</title>
<meta name="keywords" content="" />
<meta name="description" content="Guarenty Group pojišťuje příjem z nájmu pronajímatelům, kauci nájemcům - aby nemuseli platit velkou částku v hotovostí předem - a dále nájemcům pojišťuje příjmy, aby měli na nájem při nemoci, úrazu či nezaměstnání." />
<meta name="image_src" content="http://guarenty-group.com/img/gg_seal.png" />
<meta name="image_url" content="http://guarenty-group.com/img/gg_seal.png" />
<meta property="og:title" content="Pojištění pro nájemce a pronajímatelé" />
<meta property="og:url" content="http://guarenty-group.com/cz/" />
<meta property="og:image" content="http://guarenty-group.com/img/gg_seal.png" />
<meta property="og:description" content="Guarenty Group pojišťuje příjem z nájmu pronajímatelům, kauci nájemcům - aby nemuseli platit velkou částku v hotovostí předem - a dále nájemcům pojišťuje příjmy, aby měli na nájem při nemoci, úrazu či nezaměstnání [...]" />
...
</head>
THE TESTING RESULTS:
In order to trick the cache i have tested the site with http://www.guarenty-group.com/cz/?try=N, where I have changed the N every time. The strange thing is that images found for different value of N is different. Sometimes there is no image, sometimes there is 1, 2 or 3 images, but each time there is a different set of images.
But, in any case I could not find the image specified in the og:graph!
MY QUESTIONS:
https://developer.linkedin.com/documents/setting-display-tags-shares is saying one thing, and the personnel on the support forum is saying "over 300" Does anyone know What is the official minimum dimension of the image (both w and h)?
Can an image be too large?
Should I use the xmlns, should I not use xmlns or it doesn't matter?
What are the maximum (and minimum) lengths for og:title and og:description tags?
Any other suggestion is of course welcomed :)
Thanks in advance, cheers~
This answer I found on LinkedIn forums might be of help to you:
Guys, I've spent a whole day trying different things. What worked for
me is using the mata [sic] tags as following:
<meta prefix="og: http://ogp.me/ns#" property="og:title" content="{Your content}" />
<meta prefix="og: http://ogp.me/ns#" property="og:type" content="{Your content}" />
<meta prefix="og: http://ogp.me/ns#" property="og:image" content="{Your content}" />
<meta prefix="og: http://ogp.me/ns#" property="og:url" content="{Your content}" />
Just try to add prefix to every tag (not to html tag), then re-sign in
with your LI account to clear the cache...
Post your results.
I found this simple fix which worked for me after lots of complicated solutions which didn't work:
LinkedIn
The only way to “clear” the sharing preview cache for LinkedIn is to trick LinkedIn into thinking your page is a different (and new) page.
This is done by adding a made-up parameter to the link. It doesn’t affect your webpage, but it does force the metadata to be re-fetched.
Example:
Original link: //beantin.se/consultant-resume
"New" link: //beantin.se/consultant-resume?1
I was having the same issue last night. Spent hours researching solutions and I tried the solutions recommended by others in this post but to no avail. Finally I contacted LinkedIn about this issue and they responded right away. Their development team has implemented a new tool called "Post Inspector", which allows you to optimize content sharing. Literally, in just minutes this actually worked.
All you have to do is type in your URL and they do all the busy work i.e. verifying correct code of properties such as image, author, title, description, publication date etc. Not only do they verify, they also tell you what code to include, what is missing, and how to fix it.
Here is the website to use Post Inspector:
https://www.linkedin.com/post-inspector/
LinkedIn is also caching previews. If OpenGraph image was incorrectly cached at some point before, try defeating the cache with a query parameter on a shared link, e.g. https://your-website.com/?1.
Just a little late lol,
But I came across this exact issue, figured out that linkedIn was pulling the meta tags from the final landing page.
My website that i was trying to link to had an instant redirect, adding the og tags to the page where it was redirected to fixed the issue.
Make sure your og: tags are part of the head tag.
I ran into this recently, spent a huge amount of time working on it with all the types of solutions above. I was working with someone else's HTML and finally figured out that the html was simply missing the head tag, while it did have the closing tag for head.
Linked In is apparently not scanning page text for the og tags, but processing the page dom, and if the dom objects aren't properly coded, they won't process. If you have issues with unmatched tags or unclosed tags, this could be your issue if everything else is not working.
I did not need to add prefix to the meta tags or add og image height and width tags once the html was fixed. Linked In processed it fine once the html was fixed.
If you don’t want to add a fake query string parameter to your LinkedIn URLs—as suggested in e.g., #Kym's answer—a simple solution is just to sign out and then sign back in.
For me solution was to put all the <meta> tags (without prefix) inside <head> tag.
For other social networks like Facebook, Twitter or Google you don't even need to have <head> tag. (because it it optional in HTML5 specs)
PS. There is a new nice way for testing <meta> tags on your website: https://metatags.io/
After researching for a day, I found that meta tag with attribute property should be used instead of name.
<!doctype html>
<html prefix="og: http://ogp.me/ns#">
<head>
<meta property="og:type" content="website" />
...
Ref: https://ogp.me/
In my case I did exactly this and it worked fine (on my page of course).
Put these four lines in the head:
<title> aanalytics </title>
<meta data-react-helmet="true" property="og:image" content="/photos/s5.jpg">
<meta data-react-helmet="true" property="og:type" content="website">
<meta data-react-helmet="true" property="og:url" content="https://www.aanalytics.de">
BUT, pay attention that if you have more than one head in your page, these lines need to be inserted in the first head otherwise it will not work.
I also had prefix="og: http://ogp.me/ns#” in the html
I got it finally working by adding the full image path:
<meta name="image" property="og:image" content="https://hasan.life/images/preview.png">
This is worked for me.
Somehow this problem happens if you don't set your open graph tags properly.
Instead of this:
<meta name="image" property="og:image" content="{content}" />
Try this:
<meta name="image" property="og:image" content="{content}" />
<meta property="og:image:secure_url" content="{content}" />
<meta property="og:image:width" content="640" />
<meta property="og:image:height" content="442" />
I've tried for more than half an hour and I found this one which worked 100% correctly

I have followed every single piece of advice I have found to try to get this to work but all of it has been to no avail. Can someone tell me why my description/thumbnail doesn't show up? Thanks. Below is my code and the link to the site:
Meta Tags:

Thanks in advance for any help.
--2nd EDIT--
Please note that this answer doesn't work any more and is out of date. Please try the above answer.
-- ORIGINAL ANSWER--
Got it sorted. Had to use a url that is chock full of craziness:
<img src='../images/share/s-fb.png' />
--EDIT--
As some extra information, I can't remember where I originally found this information but here's what the s=100 part means:
The basic approach is you are providing a link to http://www.facebook.com/sharer.php?s=100 which is the basic share page (typically this is shown in a popup).
But I tried changing the numbers and it still goes to the same place.
As for the &p, it's just html code for &p and I think this is the array that Facebook dissects to get at the information.
To those (like me) for whom the other answer did not work:
In the <head> and </head>section, add
<meta property="og:url" content="https://www.mathnuggets.com/" />
<meta property="og:image" content="https://www.mathnuggets.com/images/fb-logo.jpg" />
<meta property="og:title" content="Math website for your gifted student" />
<meta property="og:description" content="Challenging word problems for gifted elementary students" />`
Then go to FB Linter and enter your URL there to refresh FB's cache of your page.
^^^ Refreshing the cache is important.
