This is the strangest issue I have ever encountered. I have a Mac running 10.6, and on every browser one specific background image does not show up. Furthermore it doesn't work in VMWare Fusion either. I decided to create a test profile to see what would happen, I open up the web page and voila, the image appears. Now if I were having the issue on one browser I would just dump the cache (have already done this on every browser) and try again. Obviously that is not the case here. This has got to be a serious one off, but hopefully someone has seen it before.
