I have attempted to alpha out parts from a unit sucessfully in PSP 8 but when I am done, and I save, the message saying about mereged image and only one alpha channel can be saved... I did everything which many tutorials said
Sopho,i haven't tried PSP but this is the way for Photo Shop, some areas might bee the same. the background layer has to be transparent and then you can either make a new file and duplicate onto that, or if it is already transparent, then erase the area you want to alpha out.
