go back to including the photo thumbnail data in the export file. We have the ability to fetch each thumbnail directly if there is a problem with resource consumption, but this is the most efficient way to deal with it and most sites should be able to handle the memory consumption of our thumbnail data. The original full scale photo is a different issue; these can exhaust memory even before base64.
