I'm still editing on photoshop, but now:

Ioad the images into one image
move all of the images except for the first to the left.
make that layer partly transparent. ( an action is helpful)
move the next image under the partly transparent layer and align. Manually. Do not warp it.
Delete 'about' an inch's worth of overlapping material. If you like a part of an image, keep it.
Select those two layers, make them solid ( an action is helpful), and then blend them.
Merge those layers. If it looks funny, delete more or less.

Keep on until it's done. The one below was done like that.
