Hi Will,

ok, I get a better idea... do you want to move all your images at the
same time and do the comparison, or one by one? (i.e., do you want to
have a shift of let's say 1;5 for the 1st image, and 85,20 for the 2nd
image, or do you want to move all your images by 2;5?)

Anyways, "shift" is your friend here. Be careful on the edge of the
images... you might want to remove the edges, as values are wrapped around.

Now, depending on the content of your images, you can do things
differently... like identifying a region of interest (function region),
then identify the point of gravity and shift your images accordingly...
but again, it all depends on the content of the images!
