1.	Solve : Photoshop 7.0 making the background transparant?
Answer» I have a simple black and white image (line DRAWING). I would like to MAKE everything that is white to be transparant, so that only the lines show. Currently when I TRY to move the image onto a COLORED backgound, the white background comes with it. Please help GregAlso, this is a flattened image. It only has one layer. I just want to GET rid of the white and make it transparent. GregUse Magic Wand to choose the white background and delete.
