Do any teams not have a custom photo?

EDIT: Nevermind, I'm dumb as hell

Not yet, but I can work on it if you want.

Copying our discussion on discord for documentation:

[10:56 AM] Alex - [2537, software]: What behavior do you want for it?
[10:57 AM] Alex - [2537, software]: If a team doesn't have a custom photo grab a new random team?
[11:04 AM] Erik Boesen - 1418 [Helper]: Yeah

Sure, feel free to take a swing at it.
