Get Irfanview. Free from http://www.irfanview.com , small, fast, does everything you need to resize pictures and adjust the tones for posting pictures. If you can't download it, I can email it to you (it's less than 1 Mb).
Cheap at half the price :D
BTW, I'm sitting out this round (too). I'll have to see if I can get some printed before I sign up for another round!
