ThingLink is an excellent way of creating and sharing rich images (i.e. images marked up with links, videos, comments and other interactive features). ThingLink helps you to tell stories with and about pictures. These can be shared with friends and colleagues. It seems like an excellent way of teaching students using marked up images online (outside of class as well as inside). The online and collaborative element means that students can mark up images individually and collaboratively, and share them with teachers, their peers and the wider web.
