Do you mean like ColorKeying, or alphablending.

if colorkeying do this:

SDL_SetColorKey(yourimage, SDL_SRCCOLORKEY, SDL_MapRGB(yourimage->format, 0, 0, 0));

I've had experience with color keyeing (but not alpha blending) so let me warn you that SDL does not like anything with a 0 in it as a transparency color. Choose some arcane combo like 123, 65, 247 or something instead. I think it may even be finicky about 255, 255, 255 (white) as well. All I know is that it drove me nuts till someone told me

In fact i prob have the thread bookmarked...

yup - here it is
