Well, as Fngplg said (and as I briefly mentioned on Community Central), it is more or less impossible to do this if the images are not of a uniform layout. By uniform layout, I mean that they are all the same dimensions with the object of interest in the same region of the image. From what Fngplg posted (I haven't checked myself), it sounds like your images are all different sizes. At the very least you would need to resize and re-upload them.
