A while back I unsuccessfully tried to find a script that would download all images from any Geekhack, so I wrote my own.
Found and downloaded roughly 2,000 photos from this thread, but it works for any thread on Geekhack given the URL address.
For anyone that's interested, let me know and I can send you a link to the Github page. I uploaded it with a small description
how to use it, but it should be pretty straightforward anyway.
I'll add that it won't download GIFs or duplicates. However, it can only tell a duplicate is so by its filename, so if their are images
uploaded to different pic hosting sites with different file names that are actually duplicates, it cannot tell the difference between those.
