go to your profile, pres yout profile pic,then a thing should come up ( i attached to show you if you don't know waht i mean) then press the choose button and then wait a lilttle and your libraries will come up, look for the file that your chosen picture is in and double click the picture then click okay.
Np or a easier way go over your profile, and click avatar ( i will attach picture to show you what i mean) and then do the same thing by clicking choose , i will post once again.
