Yeah, I use photoshop which makes that very easy. You might want to consider using PNG format though. JPG is a lossy format which can make you graphics look bad when you save them.

A little OT: Does anyone know how to save a png with alpha channel with Photoshop 7.0? Seems to me this option is gone.. I'm stuck with PS 5.0 because I can't find any functionality for png alpha channels in 6.0 and 7.0  Huh Huh

I don't know about Photoshop, but I use GIMP for this all the time.  Saving an image that has transparency to PNG "just works"

Macromedia fireworks Smiley

it's native file format is PNG
(or png compatible as it saves extra layer data so you can edit it, but exporting to png makes it true png)
