Ah. I thought I recalled it doing edge detection, but I haven't played with it (like about 90% of the amazing functionality :-) Are you sure, or have you checked with the Magick support folks?
I have joined pngs, but I knew the edge was exactly at the limit of the png, there was no overlapping. I can not imagine how to do it with ImageMagic with unknown overlap.

You don't have to; you select from your pile all of the pictures that touch each other and it figures out how they overlap and comes up with one final [huge] image. Way better than trying to do so by hand, too.
Good luck! :-)
Ok, I may try. Each of the three photos are about 60 Megs, very big for a tiny procesor.
:-D
