Thank you so much for this very helpful post. Didn't know how to go about the whole profile update thingy, and then I came across your post. Just like that, my problems were solved. Thanks once again.
#Update: Don't forget to add the jpeg or jpg extension at the end of the link, fellas. I forgot and the image refused to show up on my page till I eventually figured out my mistake....some very long minutes later.
Thanks @ilyastarar for such an helpful post once again.
