While checking out various sources for insightful information, I came across this enlightening subject excerpted from a blog posted by one of my friends, "Snapper" at www.theemancipatedartist.com
"Confused about image licensing?
What's the difference between royalty-free and rights managed images?
Who's responsible when infringement occurs?
Someone else created my website. Am I liable if the images are not licensed correctly?
What’s the difference between “personal use” and “commercial use”?
If you can't answer these questions quickly and confidently, you might want to take a look at a new website called Stockphotorights.com, which focuses on image copyright . While the site's primary audience is people who plan to use images for a website or ad, there is plenty of useful information for emerging photographers as well. For example, the Licensing Checklist is a great reminder to photographers not only to get the appropriate model releases, but also to be aware that things like artistic works, trademarks and buildings in your photographs may require property releases...
...the Case Studies section of the site, provides real-life examples of the kinds of legal thickets naive photographers (and image buyers) can get themselves into.
