Cover Thumbnailer is an application that tweaks Nautilus to display images as folder thumbnails, useful for regular image folders or music folders that come with cover art:
Cover Thumbnailer displays music album's covers and a preview of pictures which are in a folder in Nautilus, the GNOME's file browser. Cover Thumbnailer generates the folder's thumbnail automatically, like any other thumbnailer; you don't have to generate thumbnails manually.
Cover Thumbnailer 0.8.3 has been released today and the only change is Nautilus 3.x support (for Ubuntu 11.10, etc.).
It comes with a configuration tool that allows you to tweak the way the folders are displayed, enable or disable the previews for the Pictures or Music folders, ignore certain folders and more.
