Photo editing

Do you do a lot of editing to your pictures? What program do you use for it? I've always just cropped my pictures and tried to adjust the lighting, but right now I'm taking an online Photoshop class that a Swedish gal is hosting on a blog. I use PSE, which is quite enough for me, at least for now! I love learning new techniques, but it takes a lot of practice to get the pictures just right!

I am big on PICASA...Love it. So easy to use, and is a really awesome tool for the quick fix. I'm usually in a hurry to get my pictures done, so I can move on to other things. But Picasa makes it really easy and gives me just the right amount of creative freedom.
