Where is free image editing software like "Face on Body" and stuff like that?

Answer 1

The specialty programs like face on body are not free. If you want them, you will have to purchase them.

You can do things like they do on any image manipulation software, you just have to learn how to do it.

Here is a good one for you to try, and try the addons too. It's all free. http://www.vicman.net/
