It's a pretty big con though. Imagine if someone put something REALY inappropriate in there? Sure, we'd ban him, but if it was a little kid that saw it, then it's already too late
I'm pretty sure some of you have heard of the plugin FramePicture (http://dev.bukkit.org/bukkit-plugins/framepicture/). It's a plugin where you can place a picture from online into an item frame. I personally think this should be a ranked perk (VIP+).
Pros:
-could be useful in shops/businesses
-will allow people to show a visual of anything
Cons:
-people will put up inappropriate pictures (maybe we can limit websites?)
