Drag2Up is Google Chrome and Firefox extension that allows you drag and drop image and other files into any website input box. The extension streamlines the file uploading process by uploading your file in the background and then adding a URL link to the input box of your choice. This saves a boatload of time says the extension’s creator, a 15-year-old developer who goes by the name Antimatter15:
“Instead of the trouble of opening a new tab, navigating to your favorite file provider, waiting for it to load, pressing the browse button, navigating to the folder with your image, pressing “Open”, then hitting the submit button, waiting for the upload to finish, copy the link, find the original tab among the mess of tabs that fills your tab bar and finally scrolling down, selecting the box and pasting the URL. All to share a three megabyte file. drag2up streamlines the process into a single, swift gesture where you drag the file onto the text entry field.”
Drag2Up also supports multiple files and has support for a multitude of URL shorteners. Depending on the type of file and whether you’re using Chrome or Firefox, files can be uploaded to hosting services Dropbox, Cloudapp, imgur, Imm.io, Imageshack, Flickr, Picasa, Github Gist, Pastebin.com, Mysticpaste, Chemical servers, Dafk and Hotfile.
