Uploading Transparent Gifs

I've been trying to create a banner that streches using transparent gifs on top of a loaded jpeg background. The gif looks perfect when i save it on photoshop but as soon as i upload it on to the jpeg i get a noisey white line around the outline of the giff, does anyone know how i can minimise or erase this?

This is excatly what I'm having trouble with! I hope we get the suloution! this has been bugging me for a long time.

Is this what you're getting? If so then check to make sure that when you save your gif you set Matte to "none." If Matte is set to anything other than this and your image has any anti-aliasing around the edges then that could explain the white noise.
