Deys a great article about copyright and content theft over on BlogPaws called Malice in Wonderland. It reminded me that although da lady is very careful on her bloggy, she is a burglar on mine.
Purrrr Always assume web content is copyright protected whether you see a copyright notice or not. The notice is a gentle reminder and little more.
If you are familiar with the Digital Millennium Copyright Act, this is why it stifles creativity.

You can use the TinEye reverse image search to look for your photos online.
flickr allows authors to use Creative Commons copyrights. Da lady uses lots of them on her blog with proper attribution as required. Some allow derivative works. Some can even be used for commercial works. So if you upload to flickr, make sure to set the copyleft!
You can always ask! People will let you use their stuff if you promise to link back to their site.
Da lady uses a wordpress plugin called OpenCalais Tagaroo to find pictures on flickr and suggest tags from Reuters.
I'm a bad boi. Da lady should pay more attention to da laws in my bloggy. It will be very important when (not if) someone asks me to take someting down dat I do so right away.
