Facebook tagging is well used to link facebook photos to people or to tag the names of non-facebook objects.
We propose a system which adds tagging functionality to any photograph on any website, using facebook connect it will allow tagging of facebook friends and pages which have been liked, as well as arbitrary labels similar to facebook.
The tag would then be posted on that user’s wall for them to view.
There will also be a facebook application which allows people to view tags from all over the web of a user, and also web browser plugins which make these photos available as a normal album in the “Photos” section of a facebook profile. (for those users with the plugin installed)
This would mean all visitors to the website could tag (assuming they have facebook).
Users could also install the plugin which would then enable the functionality on every website.
