Excellent question!

I do not use any Safari Extensions (or third party plugins etc), but you got me thinking along those lines.

In Safari's Preferences, I changed the default search engine from DDG to Yahoo. Copying and pasting the bare URL opened the "page full of images" that I want.

Changing it back to DDG opened the "About" page. So, it's something Safari is doing, despite pasting a bare URL.

I thought the user's search engine preference in Safari should have no effect on pasting a bare URL, but that's clearly wrong.

Well that's odd but I'm glad that you're on the right track to resolving this!
