Is there any free software that enables one to place a dog face from one photo on a human body from another photo?

or paste a human face on dog's body?

I'm not looking for anything sophisticated. It is a joke for a friend.

Thanks.

If you post the 2 pictures here you will probably have at least 5 good examples within a day. Much easier, quicker and not expensive when you don´t need to buy the software (and learn how to use it!).

At the same time I think many will be happy to help you using their good skills!

Good luck !
