Royalty free wide format photos

Does anyone have any good sources of royalty free photos- wide format that can be used in the Dolphin image rotate for the home page.

Thanks

Rob

www.sxc.hu is great, but they don't specifically have wide format ones, but you can crop them, and they are free!

Thanks distoria - I will check it out.  I also found that Google made some great enhancements to its image search, and you can now search for profile format photos, and even search for those with no copy right.
