My gallery is now back online with access to all 17K and 9GB worth of photos at the same address as before (http://www.doesnotcompute.co.uk/gallery/).
Due to the amount of disk space required, this is hosted on a different server, and makes use of an SSH tunnel and mod_proxy on the main web server to trahnsparently forward the requests to the original server.
This also restores the pictures in my Urbex reports.
Enjoy :)
