What app allows me to paste one photo to another?

Does anybody know the name of an app for iPhone which allows you to have two or more photos, you can cut a section off of one photo and paste it to another photo? I believe there was one called "cut copy paste lite" but I can't find this.

This one allows you to change sizes and overlay on top https://itunes.apple.com/...?ls=1&mt=8 If you mean like cut out an animal or something like that, you typically need to be on a computer with professional type software.
