There used to be this archive where you could search a username and then download their galleries:
https://ia601908.us.archive.org/11/items/webshots-freeze-frame-index/index.html
However when you try to download the files it no longer seems to work.
So then I searched Wayback Machine which came back with a bunch of results from something called
ArchiveTeam WebShots Freeze Frame, which looks like this:
https://archive.org/search.php?query=webshots
Clicking into one of them and checking the file contents came up with a list like this:
https://ia600308.us.archive.org/tar...me-20121009150301/webshots-20121009150301.tar
I downloaded some and it works, you can view the users entire gallery just as it
looked on Webshots. The usernames go alphabetically in the list for this particular collection
but I can't figure out how it's organized. Clicking into other collections comes up with different
names so I don't know how it's laid out. If there was a way to search more easily then it could
possibly be a way to find some great old shots : )
