I don't want to sound whiny or anything, but.. homer, wouldn't it be easy for you to remove the white background?
Looks better without it.

Well, normally I save my files as jpg because... I'm old. There is no transparency for jpg and GIF doesn't have the level of colours I need so it would mean learning something new. I'm not averse to learning but I think I'm getting to the point where learning something new comes at the expense of forgetting something (I've run out of the human cognitive equivalent of a computer's RAM) so it's really fear that keeps me from removing the white. I'll try to grow a pair and learn how to adapt and remove the white.... but it might take some time

Save as PNG, keep the transparency, easy.
