How to create a single image from an overlay image and a picture taken with the iPhone?

Question

There are many applications that do this ... but I am curious what proposed methods exist to create the highest quality image.

An example of what I want to do:

• Ability to overlay a mustache image on top of the iPhone camera.
• It is not necessary to be able to resize / rotate this image.
• Take a picture and overlay on the image (mustache in case) to create one image.

Many thanks.
