Snaplr - Capture and Annotate Your Desktop

Vessenger, producers of a group messaging system, offers a free program for capturing and annotating images on your computer screen. The free program, called Snaplr, is available for Windows and Mac.

Snaplr reminds me a bit of Jing without the video option. With Snaplr installed you can capture all or part of your screen. Snaplr's annotation tools include text boxes, highlighting, and free-hand drawing tools. When you've finished creating your annotated screen capture you can save it as a PNG file or attach it to an email message in Outlook.

Applications for Education
Snaplr, like all screen capture tools, could be very helpful when you're introducing a new program to your students or colleagues. Offering annotated screen captures allows your students to progress at the pace that meets their needs and have your handy references along the way.
