I looked at the webpage source, found the list in an onLoad() function, at around line 310.
Yes, the URL for all 13 images are detailed there if you right-click and select "View page source" in Firefox.
I wanted to view them, so tried "View page info.", but could only view one image at a time (the one selected or default on the web page).
So I tried the image-finding tool (a Firefox extension) called FoxySpider - refer Re: Firefox Extensions: FoxySpider - useful image-finding tool
That was actually excellent for viewing not just the 13 images for that property, but also stacks of other images not shown on that particular page.Caveat:
The discussion thread at the link shows that FoxySpider tries to scan for and collect as much as it can, which will tend to make it a resource hog if there are very large-size image files present on the webpage(s) being scanned.
