GrabBox is a utility that reacts to the screenshots you take. It automatically copies the screenshots to your Dropbox Public folder, and then copies the URL to the clipboard – ready to share with friends or strangers! Just start GrabBox and then take a screenshot like usual (Shift-Command-3 or Shift-Command-4 and select). GrabBox takes care of the rest! GrabBox offers: Free hosting (via Dropbox) with no ads. Automatic short URLs, for convenient tweeting (optional). Full control over which screenshots get uploaded. Ability to specify a screenshot file-name or to let GrabBox generate one automatically. Choose between a Dock icon or a discreet menubar item.
