Hi Paul
We've got several public sites listed on the front page of our
website ("Sites powered by OME technology" in the sidebar on the right), some are also
listed here.
I think the Paris speaker you're referring to is Olivier Debeir. His talk and most of the others can be downloaded:
http://downloads.openmicroscopy.org/pre ... ris-Talks/You might also be interested in browsing through the rest of the presentations/poster from past meetings:
http://downloads.openmicroscopy.org/presentations/If you're particularly interested in looking at OMERO as a teaching tool ("Virtual Microscope") we've got an internal demo server- get in touch if you want to have a look at it.
If that's not sufficient and you're looking for medical imaging data sets try searching for
medical imaging challenges, e.g.
http://grand-challenge.org/ Many of these provide data sets for comparing biomedical image analysis algorithms.
