Convert photos to coloring pages

I wasn’t sure where to place this - hope this is the right area for it.
My son just sent me this link. He downloaded it to use for his kids. You can turn your photographs into cartoon coloring pages. He said they are loving it!
There is a fee - There are 2 versions - one is $20 and the other is $35.  He got the basic one. 
Just thought I would pass this on if anyone is interested.
