Lollipop 5.01 got pushed to my Nexus 7 2013 couple days ago.

Now I just noticed Gallery has disappeared. Everything appears to be I think all graphics was put in the photos file. Will have to look around to see if anything is missing.

Welcome to Android Central! Google finally got rid of the old Gallery app with Lollipop--use the Photos app. I think you can still see the remnants of the Gallery app if you open the Camera app and then swipe in from the right to view your camera roll. Remember that the photos aren't stored in the Gallery app per se--any gallery app will display any image that is in any directory, as long as there isn't a file called ".nomedia" in that directory as well. Most photos will be stored in the /DCIM/Camera directory, if they were taken by the Camera app.
