Picture crop

Hi there.

When I edit a picture in photos application, cropping it, it never saved as cropped. Because if you try to load it trough Pages app, it will show up original untouched. And you can not edit it anyhow, except trough 3rd party application, like Snapseed. That *****. So I am not sure, if I send a picture to someone else after cropped trough Photos app, will it go untouched, or can it be reversed to original, as it is in the Photos app?

P. S. Had the same issue on iOS 6 too.
