Thanks to
echoalpha for recommending IrfanView. It's so easy, even I can use it. I went on a rampage through the picture files on my hard drive making icons with wild abandon. None of them are terribly fancy, just cropping and resizing, but they're mine. Of course, I now have more icons than space to keep them, but let's not quibble over details while I'm basking in the glow of my tiny little accomplishment.
...but I should probably start trying to learn to make my own icons. I don't want to do anything fancy with special effects, and I don't expect to be making enough of them to justify buying Photoshop or Paint Shop. Can IrfanView or GIMP be used to make icons? Do any of you use one or the other of them? Do you have a preference?
ETA: This is the icon referred to in comment 1.
