You`re scanning line art ?

If that`s the case, you`ll need to select the lines by magic wand(click the background, Guasian blur 1 pixel) and delete, or take it into the Channels Pallette, clean it up as necessary, save the selection, go back the the Layers Pallette, and delete the background, or one of several other methods, and save the image as a transparent .gif.

If your not scanning line art, ignore this post.
