I'd try IEFIX first. Hint: google.com

Some types of images don't display
Additionally it has been reported that the use of AdSubtract, and/or GetRight can also cause this. Some users have found they must set encoding in Internet Explorer to Western European (Windows) vs. ISO so that's something else to check.
If I access my e-mail through the web browser, I can see .jpg or any other files that are attached to my mail. When that same mail is opened in Outlook Express all I get is the placeholder with the little X in the upper left corner.
I tried looking in TechNet but found nothing usefull so I figured I would try here.
Anyone have any idea's?
