first u upload 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 photo 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 upload photos on your profile page, and that's it.
