Images don't show in Firefox?

[fearfx]

why, in vbulletin 3.6.5 does images NOT show up in firefox, but show up in internet explorer?

edit: I'll be more specific, header and footer images don't show in firefox, but forum headers, and images a like show. Why is this?

IE could be displaying it because image is cached ... check the html source and make sure the image path is set correctly

It could also be bad html code.

I just had a user complaining about this.. Everyone else with Firefox doesn't have this issue but him. It's quite strange, really.

Did you figure out what was causing this problem?
