Loading remote image in firefox

Question

I've got an HTML page.

Inside an <img> tag, the src= points to an external website:

<img src="http://a.website.com/an_image.jpg" />

In firefox, the image doesn't load. However, if I inspect the element with firebug, hovering on the link will show me the correct thumbnail (as firebug does), so I know the link is correct.

Also, in Chrome the same image loads fine.

Why is it not loading in Firefox?

Additional details that may/may not be useful:

• It's a python Django application running locally with the development server
• Application: Firefox 9.0.1 (20111228084940)
• Operating System: Linux (x86_64-gcc3)

[EDIT] Plugins:

• [EDIT] Plugins removed -- no need for them, the problem turned out to be different

Answer 1

Does the site you refer to allow remote linking? Some sites disallow this by checking the referrer header. It's entirely possible that firebug is not using the referrer at all, but firefox will do it when loading your page.

In the firebug net tab, you should be able to see the request for the image. Check the response for that. Is it a 200 (http ok)? if so, is the data that is sent correct, or is it blank?

Answer 2

This is because the option "Load images automatically" is disabled in your Firefox (option dialog, "Content" panel), in such a case Firefox will only load images with local paths, not remote images.

Answer 3

For anyone that comes across this and has cookie blockers or similar installed.

I had this issue just now as well, but it turned out it was Privacy Badger that was disallowing Trip Advisor to load it's images, by disabling Trip Advisor cookies. However, there is not much you can do to stop this repeating itself on other people's computers if they have privacy software enabled.

Here's two screenshots of before and after.
