I learned about Nations Illustrated through a recent post on About.com called Thirty Free Image Resources on the Web.

Nations Illustrated has over 7,000 photos from all over the world.  They’re categorized by country, and they’re free to use for non-commercial purposes.

One of the neat features it has is allowing any photo to easily be made into an E-Card.  Students can write postcards “from” different countries, and then post the urls in blogs or online journals.

I’ve placed the link on several pages on my website, including on the Teacher’s Page, on the Geography page, and on the lengthy list of E-Card possibilities.
