Deconstructed camera from flickr.com
About a year and a half ago, I posted some links to online resources for royalty-free photos. Lately, I’ve been reading Presentation Zen (an excellent book and blog for improving your presentation skills) and thought I’d share some additional resources found therein. If you need photos for your website, newsletter, or classroom, you can use these resources to find lots of images you can use without fear of violating copyright law. (Of course, I’m not a lawyer, so read the fine print.)
morguefile.com
morguefile.com – A “public image archive for creatives by creatives” contains lots of great stock photos. For the sake of comparison, I’ve done a search for “camera” on each site. See the results for morguefile.com and the terms of service.
imageafter.com
imageafter.com – Images from “the raw base for your creativity” are not always as professionally stock looking as some other sites, but one nice feature is you can sort images by color. See results for “camera” and terms of service.
sxc.hu
sxc.hu – Stock.xchng is my personal favorite. Get access to thousands of very professional-looking, high resolution photos when you sign up for a free account. See results for “camera” and terms of service.
compfight.com – The best way I’ve found to search for photos on Flickr that are published with a Creative Commons license. Results run the gamut from stock-looking to very creative, including the image at the top of this post. This is a good place to look for something different. See results for “camera” and read more about Creative Commons.

I like sxc.hu a lot too – I have a large collection of images I’ve downloaded from there, organized in iPhoto. Much as I like using photos, sometimes I just want clipart and this page has links to clipart sites as well.
Personally, I avoid clip art at all costs, probably due to my background in art and design. I usually look for other solutions with photos or text. Of course, some stock photography comes very close to clip art. If that’s what you’re looking for, this looks like a good resource. Thanks for the comment and link.
