Hello, I also think that we need a support for high resultion images. But we should rethink if JPEG2000 and Djatoka is the right way. What's happen with the servers if we get 1000 requests per second and how free is JPEG2000?
If you use instead tiles you can use tile-caches and other server optimisations.
So I experiment a little bit with TMS[1] and create: http://toolserver.org/~kolossos/zoom-image/tms/ To create this tiles I use the opensource tool GDAL2tiles.[2] The frontend is OpenLayers which we want to use in Mediawiki so or so for the Openstreetmap-integration project.
I also test Zoomify so if you want to compare: http://toolserver.org/~kolossos/zoom-image/ but I think we need in the future no flash.
I'm very interested on highresolution pictures and use a panorama robot to create such images and would like to upload pictures like this [3] to commons. What I want to say is that also normal Commons users can create Photos with 1 Gigapixel resolution.
