Pictures Aren't Loading Properly

For example, when I go to Myspace, some of the pictures aren't loading. And also, when I was on the hotmail site, the page wasn't loading properly either. What could be causing this? Do you think Firefox might be causing this? This has been happening a lot lately.

 

What add-ons do you have active in Firefox?

 

Ad-Block plus only

Do you think this is happening because I checked in the box that says "Browsing History" on my FireFox under settings so it will delete them everytime I close my browser?

 

Do the pictures load correctly if you use IE?
Adblockplus might stop some sponsored and third party pics from loading, but the ones you (or friends) have uploaded should not be affected.
Deleting your browser history won't change the ability to display pictures, so it's not that.
What is displayed instead of the picture? Can you post a screenshot?
