Morguefile

Basically, it's a collection of free stock photos for personal and commercial use. You can also learn about photography and interact with other (aspiring) photographers. There's a small database and depending on your purposes, it's kind of limited but it's still a decent resource to reference and gain inspiration from (and best of all, it's free).

The website is easy to navigate, and easy to find images. I'd recommend it to anyone who wants photos for book covers, etc.

This is a great new site that is very user friendly. Definitely worth using, thanks :)
