I've got a lot of urls like this: https://www.newgrounds.com/art/view/alvinhew/annika where one or more images are displayed.
I want to use wget to get the images on these pages that have links like this: https://art.ngfiles.com/images/49000/49087_alvinhew_annika.jpg?f1254528733 but I'm not sure how I should configure wget to go from the first sort of url to target the second sort.
I could just open all of the www.newgrounds urls and copy the art.ngfiles urls, but that would defeat the purpose of automating it. I want to download a lot of these, and I've got a batch file that will go through them all. How should I instruct wget to look at urls of the first www.newgrounds sort, and then download everything from urls of the second art.ngfiles sort?
I don't mind if I get some extra files, like thumbnails and things, but I don't want wget spidering all over the website and potentially downloading things from pages other than the art.ngfiles links.

Thanks in advance for any help!
