I'll be honest aha. I did find it difficult to work out which is why I wanna share this with everyone.
Right click whichever photo online you want as you profile picture and click "copy image address" you can use facebook or anything like that, also any google images.
click your current image in the top right hand on the screen and hit settings, then simply hit control v or right click and "paste"
hope that helps as its very simple only once you have someone tell you, for me anything
