Initially when I joined the site we could upload our personal pictures on to our profile page and I had uploaded several pictures some of which I don't even have now...When the site went for a renovation a couple of years ago this feature was never reinstalled ..
Pay no mind to those who talk behind your back, it simply means that you are two steps ahead !!!
Everyone does not post everything their own likewise not everyone posts their own images on each site. I know that as an editor on different sites. Not all members are as honest as you are, we have to delete lots of posts everywhere. So there... But I am hopeful this feature will appear soon.
I love this free image hosting site for sharing my work
