Google Photos is finally adding a new button that allows you to flip images horizontally. This tiny addition can be found in the Crop section of the Editing tools within the Google Photos app and was spotted by a Telegram user (via Mishaal Rahman).
We checked but haven’t received the tool in our Google Photos app yet. Rahman reports that it’s only available for some users. Google may be rolling it out through a server-side update, in which case it could take a few days to start showing up for all Photos users.
Currently, the crop tool in Google Photos includes options to rotate, resize, and improve the aspect ratio of images. When available, the new tool to flip images horizontally will appear next to the rotate button. The X post above explains how the tool appears and what it does.
