Skitchin' Out!

Skitch is an image capturing and sharing application from the makers of Comic Life, Plasq. They make some great tools. Although the Mac has built in screen capturing abilities, Skitch is fun and easier to use and just more useful. Upon capturing your screen shot you can click a single button to publish it to your private Skitch site and then share it with others either via direct linking or embedding it into a forum. The private site provides quick copy links to get the right image code you need for your task.

This application has proven very helpful in my job as an IT worker. Sending screenshots to others during support procedures is very useful.
