While perusing through Danny Choo's site, I came across this link for PhotoFunia. I must say that I spent 45 minutes on this site having a blast. This site will take your portrait photo and place it into numerous photographs. It uses a face detection system and then masks your face into the photo. They even have some gif files that you can use which is even cooler.
I took a couple of my son's photos and had fun placing him in odd places and on peoples faces. He was on a billboard in Taipai, on a poster outside the Odessa Opera House and on a shirt that is being worn by Madonna. What he really liked was being Captain Sparrow from Pirates of the Caribbean and as Jedi from the Clone Wars.
Now these are not hi-res pictures which is fine for a free service - yes it is FREE! They do average around 500 x 500 to 700 x 500 pixels in size. I think this is a great size to print and send to family.
So if you have some free time and want to get a laugh at someone elses expense - you have got to go to PhotoFunia.
Here are some examples from the site:
