Please note that there are two different ways to post photos. Profile photos are placed in your profile, with one being your main image and the others following. You then have a photo gallery which is separate from your profile photos. If you upload photos to your photo gallery and none to your profile your profile will be empty of images. The gallery is a neat feature that allows you to share images and is linked to your profile but again is not your profile photos. Please let us know if you have any questions on the differences.
