Okay, so this is probably a really, really, ​really ​stupid question: how do you put photos into your stories/ set your avatar? I've been trying to figure it out for a while, and for some reason my brain can't seem to understand how to do it. Idk, maybe I'm really slow or stupid or something. But I'd really like to know, so if anybody can tell me how, then please do! Thank you so much~
