Hmmm, i assume you want to fade an image, and your asking how to do that?
Well, first off, is it an image, OR, a sprite? Basically 2d or 3d?
First off, 2d in blitz doesn't support real time alpha. Does the image move when it's fading, or does the backround change when it's fading. If the answer is no to that, then you can manually alter the pixel colour, to fake a fade operation alot quicker. Even better, create an animated image.
