App photo editing zoom

To find an pic editing app that will zoom photos, what you apparently need to know is that the digital zoom (after taking the pic), is linked to the crop feature.

Quick Pic Photo Gallery App

If you would like an awsome photo display gallery, this app is for you as it shows all the different photo folders in a really awsome way.  It has lots of other features, e.g. sort by different criteria including date.
