Click "Compress Pictures" to remove the cropped content.
Delete cropped areas of picture
Even after you crop parts of a picture, the cropped parts remain as
part of the picture file. You can reduce the file size by removing the
croppings from the picture file. It is also a good idea to do this to
help prevent other people from viewing the parts of the picture that
you have removed.
IMPORTANT This cannot be undone. Therefore, you should only do this
after you are sure that you have made all the crops and changes that
you want.
