I've been using a PHP script that a friend of mine wrote for me to display my home photos on my SuSE Linux web server. It would probably be dead easy to use it as the basis for a module to replace the default gallery, it uses the same 'convert' utility.
If someone would like to take on the relatively easy challenge of using this script in a module then I'd be very grateful as it would allow me to replace my webserver with the N2100:
index.php

// to speed up first access by not
// creating so many 640*480s. This also
// allow new files to be added after
// first access - their thumbnails and
// 640 are created automatically.

// manually rotated pictures.
