App to change faces in photos

[D0gsballs]

Hi all.

Just wondering if there is an app that allows you to edit photos and change the faces. By that i mean I have a group photo but some of the people are looking the wrong way, but i have a second photo of them all where again some are looking the wrong way. The two together though - perfect.

If you have a Nokia, it's called Smart Shoot.

That only works when taking a picture? I've already taken the photos and need to adjust them after. I suspect I'll be able to sort it on my pc
