Rotocasted, self described online library for toy collectors. Members can upload images of their collectibles and anyone can browse the over 8000 images currently stored. The images are not only of commercial vinyl toys but also of mods, repaints and stuffies. Joining is free.
Incidentally, I found this site travelling circuitous path along twitter that started with a google search of Dylan and Cole Sprouse (Disney's Zack and Cody). Dylan is an artist and vinyl doll designer. His first collectible vinyl toy (William and Shady pictured below in brown) is in release through his design company, Sprousearts.
