cut and shrunk them with paint after scanning them first as jpegs. Had to of course put them into bit maps to play with them. Tried to upload them into a yahoo phota album and was informed that only gif and jpeg formats are acceptable. same for the avatar I think.
if you resaved them at their new size/format you are screwed. you should have saved them as something else so you would have the original and the new version. sorry mister.
