Get a new preview on facebook.com - html

the last website, I created, became a "coming soon" site before relaunch. Now it is available to the public. If i want to promote it on FB and type the URL in my status line, I always get the preview image and preview meta description from the preview website!
How I can force FB to load new information from the website. It seems to be that FB stores these informations. Maybe I only have to wait a little bit longer but maybe there is a easy solution?!
Thx
Greetings

You'll just have to wait. They're caching it all heavily. Maybe try to put your URL here and it may refresh imediatelly. Otherwise, you'll have to wait

I have an SSL but the pages are not showing lock signs which I need for my order page

I have an old site I am just about well enough (broken arm + cancer) to start working on again and I have already moved it to another server OVH and added an SSL/TLS certificate to it.
However in Chrome when I visit any page on the site, especially https://www.strictly-software.com/plugins/order.asp it shows either (don't know why refreshes would change it but they do sometimes) the insecure sign with the red line through the https:// part of the URL in the address bar or an information circle.
In Firefox however I get a secure lock sign. It maybe some add-on I have used like a popup blocker or something but I am at a loss to find out what is causing these insecure signs to appear when I need locks, especially on the order page
This morning I spent hours going through loads of JavaScript and CSS (background:http://blah.jpg) etc and changing it so it is local and cannot be changed remotely as well as making any http references into src="//" or href="//" etc.
I thought it must be one of the images on the "add this" pop up but cannot see anything in their code. Then I thought the Twitter scroller might be showing images from http destinations but Twitter wraps them all in their own URL format.
Does anyone know from looking at the generated source code what is making the page insecure?
Surely there should be a list somewhere in the browser that shows what content isn't secure and offers you to load or not load it? I know the information icon lets you load or not lot Flash, images or JavaScript but do you know of how I can find out what content isn't secure on these pages without asking visitors?
Thanks in advance.

How to change LinkedIn share image in HTML?

I developed some html pages with social sharing functionalities like Facebook, Twitter and LinkedIn etc.
But now, I have some problem to change LinkedIn image.
To share on LinkedIn I use platform.linkedin.com/in.js plugin:
When I change image from image6.jpg to another JPG file in metatag og:image, changed image couldn't be shared.
Please help me to solve this.
Thank you.
I post this answer for the developers touch Linkedin first.
The other social sites have no problem like this.
But facebook and Linkedin have this problem, because these sites have cache and save the first scraping data in cache (especially images).
Facebook cache can be removed by manually, but Linkedin cache can not be.
Linkedin cache restore scraping data for a week, and Linkedin clean cache after a week.
During this period (one week) the page you want to change image wouldn't be shared.
Because as I write, Linkedin show old data in cache , and save it again, so you have to wait for a week.
Only way to change image immediately is to change page url also.
Thank you.
So, let's think about this. Here is your what I think is the kernel of your problem:
...When I change image from image6.jpg to another JPG file in metatag og:image, changed image couldn't be shared....
At first, when you said When I change image, I thought you meant changing it in the HTML, but now I think what you mean is you are changing it through JavaScript: i.e. $(metaelement).content(newimage);.
If this is what you mean, it will not work. LinkedIn is doing a blind, simple, non-JS activated scrape/parse/cURL of your webpage. If you try to change <title> or <meta> tags with JS, the scrape will not see it. This is true with almost every type of scraped URL, in every single search engine, for instance, like google and bing (changing your <title> via JS will not be reflected in the search result). This is just how the Internet currently works!

For example, this works for me:
https://www.linkedin.com/sharing/share-offsite/?url=http://www.wikipedia.org/
See, it works fine:

Google image search strange redirects

I discovered a strange behaviour in google image search. Let me start with an example:
I want to find a picture of a cat. I type cat in google images, press enter and I pick this little one:
http://www.freegreatpicture.com/files/157/1562-cute-little-cat.jpg
[I just inserted the link of the original image]. When you try to follow this link at the very first time, it will do two redirects:
Request URL:http://www.freegreatpicture.com/files/157/1562-cute-little-cat.jpg
Request URL:http://www.freegreatpicture.com/1562
Request URL:http://www.freegreatpicture.com/cat/photo-1562
The response to the 3. request content types is text/html. Basically it loads the website where this cute kitty lives. So now the kittens images is cached, if you would try one more time to hit this URL:
http://www.freegreatpicture.com/files/157/1562-cute-little-cat.jpg
It would load the image. Super! But what about when you would try this from a native client app? I mean I would want to download the image and show it in a picture box. It wouldn't load the image and you would have no idea why. It would gave back the text/html content what is not image/jpeg.
My question is, is anyone met with this problem? Any work around that to filter out this kinds of urls?

Posting of link shows correct image not until then when I waited about one hour, why?

When I create a new HTML page, I have the property tag for "og: image".
After that, I copy the link into Facebook and don't get the correct image.
When I try this some minutes later (about one hour or only 20 minutes), I get the correct image.
It makes no sense for me. Has anyone an advice?
Try using Open Graph Debugger
(Here is link: Open Graph Debugger)
after you create your post. This should basically force Facebook to process your Open Graph tags. Facebook need some time processing these tags. You can kind of automate it with AJAX to call OG Debugger, but Facebook will not like it I suppose.

Images not appearing in Facebook's share link tool

I am having an intermittent issue the Facebook share link function does not pull the the link image from the page. This is happening consistently intermittently, that is, it keeps happening but not for a consistent page, image, style, etc. I can't find any pattern. Pages won't work, and then they will. Most pages work fine at the first attempt, but maybe 5% fail.
Each time it happens I check the URL in the Facebook debug tool, and it finds the article image without problem. Often, after I use the debug tool and then try to share the link again the image is found by Facebook.
The site uses Open Graph tags that check out with the Facebook debug tool.
Here is one example page:
http://zujava.com/must-have-school-supplies
Are there other factors that impact whether an image is pulled along with a URL in Facebook?
Facebook scrapes your page every 24 hours. So on the initial go unless you like the page or send it through the debugger, the image (and other meta data) will not appear.
