Free, legitimate image editing Programs

This thread is for suggesting (and giving likes to) free programs people can use for image editing.

To edit a picture you can use is the free editor PhotoPlus6 from This is my program of choice at the moment. The only bug I've heard of is not to use the navigation window because it will crash the program. I just don't open that window. The rest is a lot like PhotoShop, not as powerful, but the price is right (how can you beat legit and free?). There is lots of help in the help menues and tutorials on the web site. You can even upgrade to a newer version for only ten dollars.
