Actually, that's not strictly true. Images can scale reasonably well,
retaining sharpness and avoiding jaggies, whenever either (a) you have a
SMALL WHOLE NUMBER scaling ratio (e.g., 1:2, 2:1, 1:3, 3:1, 1:4, 4:1), or
(b) you have a bitmap manipulation program with a fairly sophisticated
scaling engine (e.g., GIMP or PhotoSlop). Note, however, that if you're
enlarging an image, you're better off with both a small-whole-number ratio
AND a sophisticated scaling engine, if you want to avoid jaggies.

You also want to adjust resolution and size for your final output: if you
optimize it for onscreen display, it'll look coarse on a high resolution
printer; if you optimize it for printing, you could end up looking
terrible on the screen, and if your printer isn't at least 1000dpi, you'll
have tradeoffs between halftone screen size and number of gray levels.
