Over the past few years, RPG.SE has celebrated surviving the chaos of Hatmas by posting photo albums to the meta.
The photo albums are here:
The Large Hatron Collider Woolly Hatastrophe 2018: Winterbash Photo Album
The Winterbash 2015 Hatmas “Photo” Album (& maybe embarrassing yearbook)
In addition to common sense rules like "have fun" and "be nice", do we have any specific rules for making these photo albums?
What does each photo need to include?
Do the photos need to be generated as screenshots?
Can image editors be used to alter the hat's appearance?
Can a user's photos include hats that the user hasn't earned?
