I have a bunch of digital photographs on which someone has typed (or auto-inserted using some utility) timestamps using a huge ugly font (with opaque background to boot!) that's obscuring a big strip at the bottom right.
Luckily I found another set of the exact same snaps, but these have been modified as well with location names etc. inserted at the top left.
I would like to combine each pair such that the final result approximates the originals and has no text anywhere. Manually cutting strips from an image and pasting in another is what I tried, but it's slow and I have to be really careful to make sure it's accurate. I'm guessing there has to be a better way, possibly something to do with layers, but I haven't been able to quite figure it out yet.
I don't have Photoshop, so how can I do this quickly and easily using either Paint.NET or the GIMP on Windows?
