Also, when resizing a .jpg image, it's better to resize in increments rather than in one step, due to the compression algorithm used for jpegs. In other words, don't go directly from a 2272 by 1704 photo to 200 by whatever. Take it in incremental steps. My rule-of-thumb is resizing to 1800 by whatever (preserving the aspect ratio, of course, which is why I say "whatever"), to 1400 by whatever, to 1000 by whatever, to 600 by whatever, to 200 by whatever. The final quality of the image will be much better. I will refrain from explaining the mathematical reason why that's true. It's on the 'Net.
