Thanks for your reply, Chas. Yes, what i want to do is scan 1 - 4 shots on my A4 scanner and then add them together. I'm not looking for panorama shots exactly. My main aim is scanning old record covers in 4 pieces then having an auto program put the parts together. Auto Stitch used to work a treat on my pc but now I've moved to Mac I can't seem to find any. I really want one that does it automatically.
I'd again suggest Photoshop Elements. I have a friend who hunted down a legal-size scanner -- rare these days -- specifically for the purpose of compositing scans of album covers. It's too late tonight to call him and ask him exactly what his workflow is, but I would be he uses PS Elements' "merge photos" function.
