Firefox: Jpgs embedded into webpages doesn't show

Well, the problem is quite simple, I don't know about the solution though.
Where there should be a jpg showing in a webpage there is nothing. I'm not definitely sure that this is the case on all webpages, but I've discovered it on quite a few anyway.

If I instead type in the adress to the jpg I can see the picture and if I'm browsing in IE instead it's working as it should.

I'm using Windows XP.

Any possible solutions?

I managed to fix it by myself.
It was Adblock that caused the problem. A line that said /ads/ blocked everything with "uploads" in it. If anyone experience the same problem just go to the page where the image wont show, then go to Tools/Adblock/List all blockable Items. There you can see which items that are being blocked by Adblock and what line that's causing it.
