flash doesnt export gif's very well, so if you have photoshop, export it as a .png with 24 bit (not alpha channel) then open it in there and save it as a gif (make sure its 500x400 or smaller so you can post it here, unless you'd rather upload it somewhere like imageshack) if you don't have photoshop, or something else that can converta png to a .gif nicely, than export it as a gif or a jpg, it should still give us the general feel for the pic, so we can help you out :3
