I want to save a gif picture, without a background, that will match for every background color..
How can i do it with photoshop?
Thanks..

You need to have transparency while working on it in Photoshop. This is usually shown by a checkered background I believe, meaning you'll have to remove the current backround before it has any transparency.

OK i'll try it i hope that will work..
Thanks alot!

Simply create the picture in Photoshop then in the Layers palette delete the background layer and any other layer there is under the picture until you see the part you want transparent as checkered.

its always good to save the transparent image in .png format than in gif. gif alwys give us jagged edges on a graphic background and looks weird.. so png is always recommended.. saving png is also the same way like you do for gif except that u need to select png option while saving for the web (Ctrl+alt+shift+S)

take the image background transparent ie .png8 format and then save as optimized image .gif by using short cut keys in photoshop as (ctrl+shift+alt+S)
