Object images used in WotC's VTT
WotC unbelievably has a VTT in beta testing. The screen shot I saw included a number of images that I haven't seen before (neither here nor at profantasy, dundjinni, or elsewhere). I was wondering if anyone here was in the beta test group and knew more about the images used. Where they came from, how extensive the collection of images is, what license the images fall under, etc.
I don't play 4e and have no interest in using the VTT (although I'm glad to see they are finally producing one for those that have been looking forward to it), however, I would love to subscribe to the VTT long enough to absorb their image collection, if the license permits such for personal use.
