Mac Users! You will L.O.V.E. Skitch! It's a free app available for Mac OS 10.5 (sorry Windows users) and it is so easy to use! The tools are simple and intuitive and allow you to annotate and edit your photos and screenshots. Save the files by using the "Drag Me" tab at the bottom of the Skitch window to drag your image right in to a document. Bingo! It's the "Swiss Army knife of visual communication." Skitch might be the best thing since AppleWorks! Get Skitch here.
