drag2up makes file sharing on the web as easy as dragging and dropping the file from your computer onto the form you would like to add the file to. The file is automatically uploaded to a host and inserted into the field.
To access settings, take any file, drag it to the bottom right corner of the browser window and drop it on the purple drag2up settings button. This will open a new tab with the settings page.
URLs are added instantly and the files are uploaded in the background. Built in support for shortening URLs. Files can be uploaded to imgur, immio, imageshack, snelhest, flickr, picasa, twitrpix, twitpic, twitgoo, img.ly, posterous, gist, pastebin, mysticpaste, chemical servers, DAFK, min.us, hotfile, Dropbox, CloudApp, Box.net or Droplr.
