I like pics as much as the next guy, but there are plenty of us here that can be trusted. Allocvec comes to mind as does Redrumloa, Pan1K and several others.
If you're a newbie with no friends, little posting experience and don't have the gee-whiz to fill out the location part of your profile - YES, but all means.... take the extra step of photographing your goods so that we make *think* you're legit. :lol:
...and if you're new here, but have experience selling elsewhere (ie: eBay, AtariAge, Amibay, NintendoAge, KLOV), don't be afraid to point us to your references...
