Free stock photography
The good people over at Smashing Magazine have provided a comprehensive list of free and commercial stock photography websites. This is an extraordinary resource, often an invaluable one. We regularly use stock photography in Arekibo to give context and improve our template designs so this resource is highly useful. Be sure to check out the table at the bottom of the article which lists how many images are available and which are free or require subscription (and what you get for those subscriptions).
