What you need to do is make the background a totally different colour than what you will be using on your complete signature, and then make the background colour transparent. I actually use Paint Shop Pro to make my transparent gifs, because I like how easy it is. So what I do is create the siggy in Photoshop and then copy it and paste to to Paint Shop Pro, then pick the colour that is supposed to be transparent, then save it as a transparent gif. Like it truth, the top portion of my gif, when I first made it was a royale blue, then I picked that shade of blue to be transparent and that's all there is to it. The finished gif no longer has any blue in it, and is in fact transparent. I'm sure there are easier ways to do it, but this way works for me.
Oh... and if you're going to attempt making a gif like this, remember to make it quite a bit smaller than a standard sized signature, because the file size of a gif like this is much larger than a regular JPG.
