I used to be able to do this with Photo Impact but they no lobger exist..I have Photoshop Elements 7. I want to put Adam's haed on Eve's body and vice versa. Photo Impact is like flying a Piper Cub and Elements 7 is like flying a DC7 jet!
Make a selection of Eve's head, go to Layer>new>layer via copy
Access the move tool, make Adam layer active and position Adam's head over Eve's head, and resize with the corner handles of the bounding box
