Shup 0.13

Shup is probably the quickest way to share screenshots with anybody over the Internet. You can easily capture the whole desktop or an active window with this tool and then upload it directly to any of the five image hosting services included in Shup: Imageshack, Photobucket, Flickr, Stashbox and Waffle Images.

Besides taking snapshots, Shup includes a very basic graphic editor that you can use to create your own drawings and upload them to any of the previously mentioned image hosting websites.

Despite including only those two capturing modes (desktop or active window) and having support only for PNG format, Shup is probably the fastest wat to upload any image taken on your PC.
