LDraw.org 2022-04 Parts Update Now Available

[Orion Pobursky]

That link just sent me back to the announcement post but based on the rest of what you wrote I assume you mean the part preview? In that case, that page is auto-generated by a script in the PT release process. This software is old, written in perl, and not written by me. Since the release process is very manual involving many steps and I haven't really sat down to learn what each script fully does, I try not to mess with it too much. That said, if I finally get the PT update out the door (which, as I've written before, I'm well behind my desired timeline), it'll be easier to change things.
