Help with Museum Fine Art Houston

[IGUPAYITI]

Hello,
can someone help me download this:
https://emuseum.mfah.org/objects/17719/rainy-midnight
I'm no programmer and I'm not even tech savvy
It took me a long time to make the program work and I can't really find a way to download this painting
I'm mostly using the extension but it doesn't work this time
Thank you
