Upload to Imgur is a relatively simple Nautilus script to upload one or more image files to http://imgur.com/. If you try to upload an image file or any other type of file that is not permitted, the script will simply skip them.
To install, simply run the install script.
Usage is incredibly simple. Just select the image(s) you want to upload, right-click and go to scripts -> Upload to Imgur. Once the images have been uploaded the URL(s) will be on your copyboard, so just paste them wherever you want. If you have uploaded more than one URL, they are newline delimited.
