Take and share screenshots.

Snapplr is a revolutionary tool to efficiently take and share screenshots. It completely replaces Mac OS X's native capabilities and works in the same way as the system tool, but offers a wide range of options. Its main feature is to upload screenshots automatically to Snapplr.com, giving you a URL in your clipboard that you can share.
A revolutionary feature, called "Live", is the ability to select an area, a screen or a window and get a URL which takes a fresh screenshot on-demand. This means that you can, for example, select the window you are working on, send the URL to a customer or a friend and get immediate and constant feedback. Every time he/she hits "reload" in his/her browser, a new screenshot is sent.

Snapplr also offers the ability to send screenshots via mail, copy them in the clipboard and of course, save them to a file. You can select the destination of the screenshot through a small control panel which is shown at the bottom of the screen while taking the screenshot. Through this panel you can also set a delay between the time you finish selecting and the time the screenshot is actually taken.
