How to download images in stacks

I'm trying to download images from source. It is in stacks. https://radiopaedia.org/cases/ct-abdomenpelvis-upper-axial-labelling-questions

I've tried to use inspect element function in firefox developer tools, and it seems that path to the file changes every time I scroll

<img style="height: 610px; width: 610px; position: absolute; top: 20px; left: 0px;" id="offline-workflow-study-large-image" src="https://prod-images.static.radiopaedia.org/images/12503836/17780c2c930680dd5c9e9a95f1ca58_big_gallery.jpg">

this is what i get. but I would like to get whole images/.../..._big_gallery.jpg part

Thank you in adevance
