Whether you want to have serious work-related discussions about different design options or just show your friends how great your hair looked in that one vacation shot, you'll find annotating your images is a lot easier when you start using a new (free to use) site called Finetuna, which allows you to easily comment on your own pictures (and those of others) and to share the commented-on results via email or the web.

There's even a Firefox extension so you can use it straight from your browser when you spot something that has to be commented on right away.
