Dockdrop is a Mac OS X application that lets you share files fast.
Drag any file or folder you want to share onto the Dockdrop dock icon and then choose how you want to send it. Dockdrop handles the upload and puts the URL of the file on the clipboard, ready for pasting into an Email, chat program or website.
Dockdrop now integrates with the Finder, iPhoto or iTunes so you can assign a hotkey to trigger an upload of the selected item.
