Check if alternative methods for submitting images work at the moment

• Submit url to image on ask page
• Use the live profile pic on sign up page -- I haven't checked these yet ^_^

(I'm currently looking at displaying profile pics #34 so these came to mind)

they're probably okay, I just need to mention to myself cos Im curious to see 😊

I have a very rough idea for the url one — try getting file at url then write to a spot in file path

edit:
some links to look at later on
