Does anyone know of a free online resource for photos that artists can use as reference? I'm looking for everything from people, interiors, exteriors, etc.

I've been using those flickr groups that combine thousands of photos based on content.

I also use the small preview photos that are available on the pay sites.

I needed airline interiors to use for reference for a recent page. One trip to flickr and I found a group that had thousands of photos of interiors, airline food, people interacting in the plane... they have the same for offices, homes, the beach, the woods... all free.

I'll try flickr. Thanks!

That page is excellent, by the way.

It sure is! I used to clip photos and keep files, now I just google images. I even use google for comic book ref. Flikr sounds like a great idea!

If you don't need large res I Stock Photo is pretty good: http://www.istockphoto.com/index.php

I have another one that has some free high res images as well, but it's at work.

And I'll echo. That page looks great.
