I'm writing a learnr::tutorial markdown for my students, and would like one of the slides to show the latest image from the webcam on Palmer Station, Antarctica:
https://www.usap.gov/videoclipsandmaps/palwebcam.cfm
However, the field doesn't register as an image - likely because it is some sort of gallery?
I cannot use the page link, the image adress, or the image to insert into:

Many thanks if there is anyone who knows how to do this.
