Click on a "Hotspot" (one of the yellow dots) to bring up the full resolution image at that location. Warning! Be careful about zoom level on this page! The refresh speed depends on the number of hotspots to draw. For this dataset, there are so many spots that it gets unusably slow if you zoom out all the way. Use the navigator in the upper left corner to see where you are in the full image rather than zooming out all the way.
