Here is the older style Gallery apk which you can install in O2. Works perfectly and also solves the Pushbullet issue with the stock O2 ROM having moved photos to the camera app, so Pushbullet does not find your 'photo' directory/directories when you try and select one. Another work-around is to select a 'file' to send, and then navigate to the photos directory, however, installing Gallery seems a more fluid solution.
