Linux Scanner Server

Linux Scanner Server is a CGI web application that allows you to share multiple scanners over the network. Since the front-end is a web app, you can access the scanner from any computer with a javascript enabled browser.

Features include:
Select scan size; rotate image; scale image; set output type as color, grayscale, or b/w (line art); scan to jpg, tiff, png or txt files; scan from multiple scanners; view all scans on separate page; change color scheme; save/restore scan settings

You can see if your scanner is supported by searching for it at the SANE website
