See every turn before you choose
Left and right are easy to mix up, and a mirror image is easy to confuse with a turn. The card draws each option on your own photo with the same steps the saved file gets, so the tile you tap is the picture you download.
Some phones save a selfie as a mirror image, so writing in it reads backwards; Mirror swaps left and right to fix that. For a photo lying on its side, Rotate left or Rotate right is the fix, while Flip vertically turns the picture into its own reflection, top to bottom.
