SPGrab is an efficient screen grabber utility that uploads screenshots to a selected FTP server of your choice and copies the URL to your clipboard for easy sharing.
SPGrab allows for screen captures to be uploaded to the SPGrab FTP server or to a personal FTP server. Unfortunately if you decide to upload screenshots to the SPGrab server, you've got no way to manage or delete your photos. The file URL can be copied to your clipboard or opened within your browser for easy sharing.
The lightweight program has configurable hotkeys for on-the-fly screen grabbing. It saves the screenshot directly as a file on your computer in PNG or JPG format, bypassing through any image editors, although the option to save images to the clipboard remains. SPGrab is freeware for Windows only.
