Free photo resources for campus clients

It's not uncommon for our office to get requests for stock photography, both of our campus and for more general or random topics. Others won't ask--you might just discover photos of unknown origin when you least expect it. Here are some resources to keep you in the clear with copyright:

• Flickr.com: Refer campus users to your own feed of stock photography for your university or school, and let them check out the Creative Commons-licensed images for other topics. Remind users to assume that all photographs are protected unless they see a license that says otherwise.
• Stock.Xchange: This site includes thousands of free stock photographs of varying quality, but a discerning eye will find some great images. A free account is required to access the high-resolution download pages.
• CVBs/Chambers: If you're promoting your campus location, check out your state or local convention and visitors bureau, or perhaps even your chamber of commerce. Large metropolitan areas or tourist regions will often have a photo gallery that's open to local businesses to use, but again, make sure to follow their licensing procedures.
• Wikimedia Commons: Most Wikipedia pages include images that are a part of their Wikimedia Commons collection. Wikipedia doesn't own these images, but most can be freely reused outside of Wikipedia so long as you follow the restrictions stated by the owner.
• Government agencies: The public information departments of many federal and state agencies include photo galleries with free high-resolution images in the press room sections of their websites. Usually, attribution is all that's required to use these images.
