What is the easiest way to re-size a picture in order to use it as an avatar? I normally use Irfanview to edit my photos, and tried sizing it down to 150x150 pixels, but my pictures are usually still 38k or so and the max is 10k. If I get it to 10k, it's the size of a dime, LOL! Chris did my last one for me, but I would really like to get the hand of this myself. Thanks for any replies!
