If you mean transparencies on a skin, then yes. Read the FAQ, it's all there.
If you mean transparencies in GIFs, then yes also. In Photoshop, you first convert the GIF to Indexed Colour, then go to File -> Export -> Gif89a Export, then choose the colour you want to have transparent.
In PSP, I'm guessing it's something similar. Check the (Ewwww) Help file. (Ewwww) (Ewwww)
ps. Help file - ewwww.
live short and hack well
