I stumbled upon this application called Jing through Slickdeals.net which is free.  It is a program for the OSX or Windows which records a video or takes a still shot of your desktop.
The best part of it, is that after it captures, it uploads it to Screencast.com to share.  You can also set it to upload to Flickr which I tested to put the picture above or FTP or to a File. (I captured this post.)
It then automatically puts the URL to your capture on your clipboard to share easily.
Here is a video capture I uploaded to test – http://www.screencast.com/users/LESLIEx317537/folders/Jing/media/4cbdf76d-a860-409b-9780-67e2a876e725
