I need *something* to align the images, yes. The scanner isn't replicating 
the exact position.
I tried align_image_stack, but it would refuse to work with images of 
slightly different sizes. Which I don't really understand, because it's 
identifying and moving control points, which includes moving some pixels 
beyond the image boundary. So I'm wondering what it's doing - clipping them?
It's not a big deal because the page margins are white space anyway, but 
I'd like to understand what it's actually doing. Is it considering the 
image border to be all control points?

The idea is to align the scans, combine them in a way that makes use of the

Good pointer, thanks.

Now you wander from the subject. Keep on the track.

Gimme a break!
First you complain it's too vague, now I'm providing background and I'm too 
off-topic for your taste...

Ah, the joys of too much editing.
I tested with PNG and found that 300 dpi with the right settings are small 
enough. TIFF with one of its compression modes may work, too, but I know 
how to convert TIFF to PNG so it's pretty much a solved problem - but 
there's that constraint that I probably cannot go above 300 dpi, 
storage-wise, so this constrains the options a bit.
