This ancient Google archive hasn't been a dependable source for images in a long time. As far as I can tell It's not maintained by either Google or Roll20. Images from that archive disappear without warning, often leaving orphaned "invisible" tokens or other graphic items that have to be repaired or purged from maps. I suggest that it either be eliminated or replaced with a real internet image search option.
