Any way to DL/Save all Screen-Caps in batch???

[MackZatis]

Basically, I wish to save all the screen caps for a scene without having to individually open and save each image. I have the add-on "DownThemAll' and use it on other sites often. But those sites images are all in sequence, and here they jump around randomly. I'm pretty computer savy but no savant by any stretch. If someone could explain to me what I'm missing or doing wrong I'm pretty sure I'll be able to pick it up. Or maybe point me in a general direction as to where I can figure it out, I'd appreciate it greatly. Thanks in advance....
