Aha, here it is. In the event that the links above don't work, here is a last-ditch effort that should work for anyone in the future needing to get these files.
PLEASE attempt to use the Drive links above instead as that will hit Google's servers instead of reaming the poor TLHH.
Attached to this post is an HTML file. Download it to your computer and open it; it will immediately start loading the ~3000 card image files in your browser window. Right-click in the blank empty space and go to "Save as" (in Chrome) or "Save Page As" (in Firefox).
Then when the dialog pops up, choose the folder location that you want all of the images to go into and save it as type "
Web Page, complete (*.htm, *.html)". The html file will get saved there, and you'll also see a "lotr-tcg-images_files" folder right next to it. This will fill up with the ~3000 jpg files, which you can browse freely in the future using that same *.html file you just saved.
Once you have done this, be sure to only use the new html file you saved as that will look at your local files instead of blasting TLHH's bandwidth costs into the stratosphere.
Once again, use the Drive link above if it isn't broken (and if it is, please message me to fix it), but if all else fails this method should work indefinitely into the future, so long as TLHH itself is around.
