Just noticed this about Saved Pictures

[CamiKitti]

In WP7.5, you were able to use apps on Saved Pictures, but either the update took it away or Microsoft removed that ability in WP8... I don't edit my photos often, but why did they remove that?

I can use apps on saved pictures on my 820, not on screenshots though. Need to open the app and then open the screenshot if i need to edit.
