Forum Viewing Issues

I've beed seeing weird images when viewing the forums on my laptop. The most obvious is the file http://forums.gotwoot.net/gotwoot/im...ad_dot_hot.gif which I see as the logo from The Incredibles on the laptop, but as an envelope on my desktop. I'm using Firefox 1..5 on both.

Also some buttons, like the post new thread button are showing up as only text instead of was visuals. Any Ideas as to what might be going on?

sounds odd to me. Try clearing cache, for starters... don't know what else to say beyond that. Maybe try a clean firefox profile, or see if you can replicate the behavior in another alternate browser (opera?).
