Zillow Image Downloader

@VeniceNerd I see this issue as well. That particular listing looks to be using Zillow Showcase ShowingTime+, the ST+ in the lower right hand corner, some kind of feature they're promoting to realtors. Just for comparison, looking at nearby 27556 Antelope Dr, Santa Clarita, the listing looks normal, non-ShowingTime+.
. If I try again for 27555 Antelope Drive, but this time on Redfin, I notice the 'lightbox' structure may be accessible. I also see that its not Santa Clarita, but Canyon Country, but that's probably not important. You might try the script on Redfin, I have no clue if its particular to Zillow. If it doesn't work then you'd need to appeal to the programmers in this thread; I don't know anything about it. YMMV, Regards,

I'm not sure why my attached Redfin image didn't load, is there a limit? I'll re-post it here in a new comment.
