It's incredibly easy to generate thumbnails (like a proof sheet) of digitized images using KDE 3 on Linux.
Open the Konqueror file manager. Navigate to the directory containing the pictures. Go to the Tools menu & choose Create Image Gallery.
A few minutes later, you'll have a new directory titled 'thumbs' that contains thumbnails & a new Web page that shows every thumbnail along with a link to the larger image. You can also have the Web page display the image filename, dimensions, & file size.
Pretty darn cool.
