[AC Question]

I save pictures from an app 9gag. It right away doesn't show in photos.. .. right now I have 3 days back pictures.. not the ones I just save. Help :/

Welcome to Android Central! Use a file manager to find out which directory those photos are saved in. If that directory has a file called ".nomedia", delete it. That should make the images appear in a gallery app.

If not, just restart the phone. Media Scanner doesn't fire for most apps (or you'd see lag you wouldn't believe), so it doesn't know that you added pictures. Restarting the phone causes Media Scanner to run.
