I really don't think it's possible for them to receive pictures or anything more complex than basic text. Anyway, I doubt there would be any way to enforce it. I think if jagex brought in a system where you could send a screenshot in, they would be overfilled with noobs sending in pictures of them going "LOOK LOOK, THIS GUY KILLED ME IN BH UNFAIRLY, MAKE HIM GIVE ME MY STUFF BAK PLLLLZZZZZZ" Which is why Jagex needs to start enforcing the "misuse of customer support" rule, and start taking away the reporting ability of kiddies who misues it. Unfortunately they will probably bring out some new crap stronghold near barbarian village again to help us understand it, even though everyone doesn't pay attention, we just get out as quickly as possible and claim the reward.
