As for the button to change the background, should it be like this:
Or possibly like this, kinda like the edit post button is:
Or should it be down with where the edit button for the avatar is?
Update: As I am new to Ruby and Ruby on Rails, im taking my time to analyze the structure of how it works(very confusing at first =D )
So far, Ive added the db column profile_background (suitable name?), added it to the serializer and user.js model + handlebars file.
Now I just have to add the user frontend for adding link(currently no upload feature, I think these images could get quite large, unlike avatars), and do proper sanitizing of URLs to avoid injection. (Any help on what functions exist for me to use?)
