OmniCoin community now has a sister site dedicated to
banknote collectors - http://BankNoteBank.com

In addition to all the OmniCoin website features, BankNoteBank
will allow you to store two 600 by 300 images per listing.

BankNoteBank membership is separate from OmniCoin. You
will need to join BankNoteBank in order to upload images
from your collection.

BankNoteBank database can be used as free web space for your
images. Linking images from your online collection to other
websites, forums or auctions is permitted.
