YAFSScreen

FSScreen watches the Windows-Clipboard and saves every image that gets copied to it to a file on your hard disk.

YAFSScreen does the same thing as FSScreen does, but has a few features to separate it from FSScreen. It can save a single image (or other data that have been copied to the clipboard) in multiple copies to several directories.
It does not remove the data from the clipboard as FSScreen appears to do. When saving images you can select from (as of now) three formats (BMP, GIF and JPEG).
