One application to rule them all. If you regularly take screenshots of Windows or the Desktop, edit them afterwards and upload them to a free image host you might find SHUP helpful. The software has all those functions build in which means you do not have to open two or three applications to do the same.
The typical process after configuring the settings in SHUP looks like the following. The user presses a hotkey which either takes a screenshot of the desktop or the active window. That screenshot is then displayed in a basic image editor where it is possible to resize the image, change the filename, tags, image format or use a rectangle to edit and upload only a selection of the image.
The image will then be automatically uploaded to the default file hoster and the url of that image automatically pasted into the clipboard. That’s a fast and easy way of creating and uploading screenshots.
Six file hosters are currently supported including Flickr, ImageShack and Photobucket. Some require usernames and passwords that have to be added in the configuration, the upload will obviously fail otherwise.
My suggestion would be to turn off all those confirmations to speed up the process a little bit. Shup adds itself to the right-click menu as well. Whenever you right-click an image you can access SHUP and use it to upload the file to an image hoster which is a very nice bonus.
I was not able to figure out how to upload images directly without having to open the image editor first. Think that is not possible.
