Deleting photos from your gallery to an album is a simple process that can be achieved in a few steps. Firstly, you need to create a new album by tapping on the three horizontal lines in the top left corner of the Google Photos app. Then, tap on "Create New Album" and give your album a name. Next, open your gallery and select the photos that you want to move to the new album. You can do this by long-pressing on one photo and then tapping on the others. Once you've selected all the photos you want to move, tap on the three vertical dots in the top right corner of your screen and select "Move to Album". Finally, select the album that you created earlier and your photos will be moved from your gallery to your newly created album.
