I *think* I understand, but I'm not sure.
Say I have a picture that's about 3" x 3". Another is maybe 5"x 5". I want them to show up at the same size on a kindle. What dpi do I scan them at? I know how to size graphics in Word, which is what I'll do my layout in before converting to a PDF - I'm pretty sure that sizing them in Word won't change the printing dpi. But how do I size them for the kindle?
