Image requirements for a CS. Not that it's the GM's fault, it's their decision I guess, but I'm just so bad at it. I much prefer a description over an image because I know what the character looks like in my head, and finding a good image that matches can be hell.
Sometimes it hangs me up to the point where I have to delay submitting a CS. I get why people use/need images for their character, it's just not my bag.
