I can't resist the temptation of playing with pictures without having to paint. I used Marylin Monroe as an example here and turned her into a pretty witch
I used my favorite program Microsoft Picture it - Publish it. It is an easy version of Photo Shop. I love it and use it so much; I have an extra copy of it - in case something happens to the program I have now. When ever I scan and crop a painting of fine, I use this program to contrast and size my art into a perfect jpeg for future storage.
