How do I flatten the back of an image of a cover to a book that is on JPG. how to i flatten the font on it back The font is written directly on the back of the image - it is not a layer I add. i know that if i add a new layer - it will ask me to merge. but here i am writing directly can i flatten it or do i need to use the layer on the back of the layer to get it done thanks Marily
