Superfluous asset folders

[ClaudeMetz]

It's a bit annoying that the thumbnails each need their own folder in here. I think that is a remnant from when we didn't store images for the articles off of Github, but now it serves little purpose.

It's a tiny annoyance each week, not sure how much work it would be to change though. The solution I have in mind is to have it just be one folder and we'd give each thumbnail a unique name that includes the issue number.

Actually locoing at code .... well it does not matter where thumbnail is located.
It literally can be any valid url.
so mostly it's a matter of cleaning up
