First of all this is a realy useful tutorial, and it's good that you also made a video for it, because I see this question gets asked alot, people that don't know how to get their picture uploaded and many people fail to get the good link to use for their profile picture.
In some languages www.imgur.com may give an error.
For the people who can't open them there are alot of other good uploading sites, like:

@Fady21 you may want to add them too, because whenever the person is noticing he can't use imgur he is getting in panic and don't know what to do, once you add them he or she has more options to choose from.
