How do I to make an absolute URL that refers an image into my root repertory app ?
I've tried this using /projetForum/WebContent/images/angry.gif as URL but it doesn't work.
str = str.replace(":D", "<img src=\"/projetForum/WebContent/images/angry.gif\" title=\"heureux\" alt=\"heureux\" />");
Thanks in advance.
When looking closer at the URL which you attempted to use, the presence of /WebContent folder is suspicious. This is recognizable as default web content folder name of a typical Eclipse web project. This in turn suggests that you actually used a local disk file system path relative to the IDE workspace root folder in the <img src> and somehow expected that it represents a valid URL.
This is wrong. It's the webbrowser who has got to download the image by a valid URL once it encounters the <img> element while parsing the obtained HTML output. It's not the webserver who has got to magically inline the image's content based on local disk file system path or so. That's not how HTML works.
Provided that the webapp's context root is projectForum (and thus the whole webapp is available on http://localhost:8080/projectForum/), then the image should be available on the following URL http://localhost:8080/projectForum/images/angry.gif. Try it in your browser's address bar first.
Once you found out the right URL, then you should substitute exactly that absolute/relative path in the image's URL so that the generated HTML output ends up like this:
<img src="/projectForum/images/angry.gif" />
By the way, the smiley :D does not look like angry to me.

I have an html file in which I would like to display an image called plot.png with the line <img src="plot.png" alt="Stock price vs. predictions graph">. On my website, I only see the alt text, meaning that my image did not load properly. In my command prompt output I see that I have a get request to /mysite/home/AAPL/plot.png, which is extremely frustrating because this means that when I search for the image this code is just placing it in the url (which is localhost../mysite/home/AAPL). I have tried putting plot.png in the same working directory as my html file as well as trying the absolute path to plot.png starting with C:, but nothing seems to get the search out of the url. Please help, thanks!
If it helps, im using Django
You can put the image in the same working directory (in the same folder as your html file) and then use
<img src="./plot.png" alt="Stock price vs. predictions graph">
The "./" is important as it signals that the image is in the current folder.
You could also use a website like www.linkpicture.com to generate a link to host your image and then use that link in your img
Some web browsers automatically disable images from loading. Fixing this could be as simple as selecting “show all images” from the browser's settings menu. It's also worth checking if the device you're using has security software or extensions that could block images.
Again you can use this tag for .png type photo
<img src="exampel.end">
//use extension type .end instead of .png
I forgot to mention that I was using the Django framework and the html templates work much differently than regular html files do. In Django you must put the image in a static folder and then call if with Jinja like so: <img src="{% static 'mysite/image.PNG' %}">
My website on my server does not want to show the on server saved image.
The path is relative and to my information correct, but I always get a 404 error.
Found no solution after browsing endlessly.
All nessecary information is found in the second picture posted.
Apparently, you use a Framework. The file you have in the view folder isn't the one you send to the browser, it's just a source file that will be used by your Framework entry point: public/index.php. Your root folder is therefore public.
Two things must then be understood:
Even though the line your type is in application/view/index/index.php, the browser will only see it as index.php, located at the base of your site (http://localhost/index.php or somethig like that). The relative path must therefore be written as relative to public.
As your root folder, public, is seen as http://localhost by the browser, you can't use .., there is nothing above the root of your website, for the browser. You must do one of the followings:
Place your image in public/_images instead of application/_images (normally, all the files that can be sent without passing by the PHP preprocessor can go in public)
Place it wherever you want and create a controller that maps a custom URL to your image. Something like /images/(:any) maps to a controller looking into your specific image folder (please, don't, it's not because you can that you should).
My advice: create a public/img folder and place it your images, then you load it with <img src="/img/title_image_me.jpeg" alt="My picture">. (The initial / is very important there!, it's understood as the root folder of your website, Linux-style).
I am trying to load an image locally onto my html. I first tried serving an image path through a /images/ folder, but that did not work. I then tried serving images with the whole path to the image like <img src="/Users/code/src/code/go/src/websites/website/website-Bucket.png" alt="test"> but I still had no luck. I checked my html and it has no errors. I have restarted my PC, changed the image to .jpg, and it still did not want to work. I get an error in Safari - An error occurred while trying to load the resource and the image shows as a blue box and question mark. What things would you try to troubleshoot?
Extra - I am using goLang to serve the files. I have it so a http.handleFunc() goes off and serves the images folder when it is requested. The path is showing http://localhost/images/theImage.png "the correct path" but nothing happens. So, I save the image and it shows it as a html and shows a section of the page?? Would that be a path thing?
In first instance you have to understand the path source, when you are on a HTML file, your path inside the file should be :
<img src="images/website-Bucket.png" alt="test">
that's because :
the path of your .html file can access trough files the inside path with the "/folder/file" structure route in the html file, so your structure files should be:
yourfiel.html (your file render on browser) /imagesfolder
-website-Bucket.png" (you call it on your html as
/imagesfolder/website/Bucket.png)./
you can learn more about paths here :
http://www.coffeecup.com/help/articles/absolute-vs-relative-pathslinks/
Looks like it may be a file path issue.
Take a look at this page it has a good example.
https://www.w3schools.com/html/html_filepaths.asp
Also try renaming the image with a _ and not use the -.
Open Console in any browser and see if you see any errors that mention not being able to find the source path of the picture.
It should give you a hint of where your browser is trying to find that img.
All of your guy's responses were correct. I had the correct path. It was a Golang thing. I did not make a handlefunc when the server wants the /image.png. It was never serving the image, it just was doing nothing with it. Thank you for the responses.
I am checking the source of a webpage whose url is
http://localhost:12345/web/query?name=time&
In the source of the html webpage, I saw a relative url:
Date
Is the relative url in the source supposed to be appended to the url of the webpage? In the above example, is it
http://localhost:12345/web/query?name=time&./query?name=time¶ms=3
Or is how to interpret the relative url in the webpage completely up to the author of the webpage?
When a web browser renders the webpage, the web browser interprets the relative url as
http://localhost:12345/web/query?name=time¶ms=3
I wonder how the browser can guess how the author interprets it.
Thanks.
./ is relative to the directory the file is in. I'd never use paths like that personally.
If the file is /web/query then Date and Date would essentially be the same thing. Obviously that link has to be found at the first level inside the /web directory or it wouldn't point to the right place, which is why I never use those type of paths, I always use paths that start at the document root, /.
These types of paths are usually found when developers either can't or don't know how to set up a proper web server for the site in my experience.
I'm loading an image on the page with a 'file:///some_dir/image.jpg' src path. I can access the image in a regular tab using this path. Also, saving the page as HTML and using this path for the image works. However, the image does not load on the live page. In chrome it shows part of the alt text, and in firefox it shows a narrow strip. I have tried changing width and height but to no avail. Is there something I'm missing?
<img title="Click to enlarge" src="file:///Users/Aram/uploads/profile.image.985b0f707d972bf3.4372696242656464696e67616e645465657468696e67437269625261696c436f7665722e6a7067.jpg" class="profile-image">
EDIT:
I noticed I am getting this in the console:
Not allowed to load local resource
Is there any way around this?
EDIT 2:
Since I could not access the image through an http path, I have decided to read it in as base64 data. For anyone else using web2py or another Python framework:
# Load the image data
import os
path = os.path.join(request.folder, 'uploads', filename)
data_uri = open(path, 'rb').read().encode('base64').replace('\n', '')
data = 'data:image/png;base64,%s' % data_uri
return html.IMG( _src=data, _class='profile-image', _title='Click to enlarge' )
Websites are not allowed to use local files on the user's computer. Use a relative path to from the html file's directory.
You can also encode and embed the image directly:

The problem is you are trying to load a file directly off of a clients computer. Browsers prevent this.
You can read about the exact details here:
http://en.wikipedia.org/wiki/Same_origin_policy
It is called the Origin Policy. It prevents malicious sites from directly loading files off of a clients computer. Try using a relative path from your page to display the image.
In some situations (rare) I've used a light web server to host the site so that I could load the files from the server (as opposed to having it load off of what the browser sees, as a clients computer).
