Click through to look at the zoomify links in your browser. The JPG files are probably too large to view in the browser (for me they appear as broken images). Right click and "save as.." to download the JPG links. Same for the geotiffs, which are in .zip files and are extremely large.
Note on processing: Some of these were processed in Feb 2013, though without the links to the high-res images. Improvements to the code and access to increased processing resources has allowed a reprocessing in winter 2015/2016. The original versions have been left here with a yellow label (original version Feb 2013) and the new versions have been posted with a green label (processed Dec 2015). Not all original versions were reprocessed, but the links to the high-resolution images were all done in Dec 2015.
