Where can I find images that can be used for free?

[Crystal Pegasus]

Can anyone direct me to sites which have photos that are free to be used on websites?

I think I've heard that there are some sites which have photos where the owners of the photo are happy for it to be used, just with a mention of whose it is, or sometimes not even that.

Thanks for any suggestions.

You can start with wikipedia and wikipedia images, those are all free to publish with or without mention of author, some you can edit (beyond changing size) some not.
Searching for royalty free images in a search engine gives mostly results for volume cd´s that can be bought at various prices. Look out for the terminology that is used to describe the types of release format you are seeking. Try lots of different searches with and without "".
