first u carica a new picture and then there would be 2 pictures below the picture, click the one that has a shape of a human, then its done! i hope this helps!
I don't even know how to add a foto on my gallery this past few days... but I knew now. I don't know if this wwas the true process. 1st, snip that picture, click carica foto on your profilo page, and that's it.
