The Photo Editor lets you customize images in your Image Gallery.
Choose the type of change(s) you want to make. When you finish, press Save New Image to permanently add applied changes to your photo.
Change the Rotation
If you want to change how your photo lays on the page, press Rotate to rotate or flip it. Rotate a photo 90 degrees in either direction as if you were spinning it on a tabletop by pressing the appropriate option. The mirror options let you create a "reflection" of your photo. The dotted lines in the icons indicate the location of the "mirror" in relation to the photo.
Crop the Image
If you want to get rid of part of the photo, press Crop. You'll see a grid overlaying it. Press any of the grid's corners and drag to change its size or shape, or press the center of the grid to drag the whole thing to a new location.
