I'm looking for a system with which can embed a zoomable image in a web page. This is for an educational site and the images are x-ray photographs - so we'd like to display the image full size then allow the user to zoom in to see the detail. The final images won't be that large - I think 2048 square should cover it - but large enough we don't want to display everything at once. Something like MrSid would be ideal.
ideally we're after a FOSS system, and one that should display on PCs and Macs - and ideally linux too. Java or Flash based would be fine. Certainly nothing that is IE only (although has to work on IE)
I would imagine anything suitable would be language independent, but for the record we're using PHP.
