The Photos app on the standard Facebook site includes a handy feature for flipping pictures clockwise or counterclockwise. You won’t see this feature on Facebook’s mobile site or Android app, so when uploading your pictures from an Android, you have to rotate portrait photos on your device beforehand. Androids rotate photos using Gallery, the phone’s native image viewer. This app also carries out a few other simple functions, such as cropping images and displaying image file data.
