A friend asked about online repositories of photos that can be used for academic presentations and I mentioned several sources. I realized after sending the list that many others may not know about the wealth of resources available, especially for teaching and learning.
Online photo repositories (check usage rights for each):
Free images for your inspiration, reference and use in your creative work, be it commercial or not! http://morguefile.com/
Creative Commons search, but check license of each photo: http://search.creativecommons.org/
Commons project from various institutions, including The Library of Congress: http://www.flickr.com/commons/
Wikimedia Commons, with many public domain images: http://commons.wikimedia.org/wiki/Main_Page
Updated:
Most of the media in these collections are attached to generous copyright licensing. http://copyrightfriendly.wikispaces.com/
I like http://www.compfight.com and http://flickrcc.bluemountains.net/ as well.
Harold, a suggestion of yours some time ago led me to the CC search on Flickr. Fiddling around, I found a way to search for CC / commercial use / adaptation images (I needed that for a client project). I then dragged the URL onto Firefox’s toolbar so I can hit that combo any time I want. This is it:
http://www.flickr.com/search/?q=&l=commderiv&ss=2&ct=3&w=all
You should still check the license, in case someone has an oddball requirement for acknowledgement.
Thanks, Dave; I’ve used that myself a couple of times. Good idea to still check, especially if you’re using it for commercial purposes. Saves on legal costs 😉
