Some pics show up with firefox, but not IE ???

[geoi310]

Hello, the following pics sometimes show up with IE, but always show up with Firefox...
Other pictures always work.

What do you think the problem is?

Examples of pics that sometimes show up in IE, but always show up in Firefox

This picture shows up all the time under either browser:

I can't see any difference in the source files, upload circumstances, or anything to set them apart.

Any ideas???

I want all pictures to show up with any browser of course.

Thanks

Looks fine on Windows XP with IE6. Might be a browser cache problem?
