If you want to use these images: Go ahead. I've placed most of them in the public domain. However >>> While most of them are public domain, a few aren't. Be sure to read the license under each of the enlarged pictures. If you have any questions, please ask.
If you need a hi-res version: I am slowly going back into the archives and making hi-res versions available for a small fee. The photos with such a version already will have a link on their detail page. If you need a hi-res file for a photo that doesn't have one yet, please let me know and I'll try to upload one. Details on the contact page.
