Files named Thumbs.db are image cache files created by Windows. They store small versions of the images contained in the folder.
Thumbs.db files help speed up image browsing within a folder, since the image thumbnails don't have to be recreated each time the folder is opened. These files are hidden by default, but may be seen if the "Show invisible files" option is checked in the "View options" window.
