[Therion] zoomify

I just tried to get zoomify to work on my webpage for a cave drawing. It only works for jpegs, not pngs. Is that right? Meanwhile, I have some technology for generating 3D renderings on a webserver and showing it through a normal browser without a plug-in. If anyone has the time and inclination to generalize it into a zoomable and rotatable cave viewer, let me know. http://www.freesteel.co.uk/cgi-bin/adaptiverough.py Julian T. http://www.goatchurch.org.uk/tunnelx/index.html
