A little note: Gladysclump said: "Most images look crappy crunched into 200x200, because the dimensions don't match."
You do kinow that you -don't- have to use the entire 200x200 size for your thumbs, right? Usually, if my pic is a 'portrait' dimensioned pic (often 3 wide x 4 tall proportion), I make my thumbs to that proportion. Thus, a thumbnail of 150 wide x 200 tall is useful. That way, there is an indication of the final pic size, and if I do a full preview of the pic, there is no distortion.
