I'm exporting gif files for my friend so he can place them on the website. I thought i was exporting them properly so the image would be transparent for him to use. any advice or suggestions? Maybe he can do something on his end? thanks

I am not clear what the problem is here. Have you tested the transparrency of these gifs at your end?

Browser: Firefox3.0.5

yes, on my end but when he tries to place on the website they are not. I apologize for the lack of information.
