Ahem. Not a staff member (so hopefully I'm not doing anything wrong by posting here... If I'm not supposed to, I apologize), but I can say from personal experience that I have never used an RPing site, nor been in a specific RP, that required a picture to be included in every post. I've used pictures in an RP, of course, but not every post. And I've never seen that posted as a rule anywhere on here. Of course, that is something you may want to discuss with your partner (if it's a 1x1), or with the GM if you're joining a group, to ask if this is something they expect in their story. If it is, and that isn't something you're interested in doing, simply avoid that group. Anyway, I hope that helps. But as I said before, I'm not a staff member, so you may want to wait for one to either confirm or correct what I said.
