Small Local Update

I added a couple photos to Illinois's I-80 page...photos that should have been there a long time ago.  But now every exit on that page for I-80 has a photo!  I also changed the cover for the Illinois pages for US30 and US52.  Remember that some thing very very large is coming hopefully later in 2023, and I've been working on that as well!

I fixed up the thing I was testing on the US31 Michigan page.  Let me know if you think it looks okay.  I'm working on a way to add more photos to some pages if I have them.

I have updated the cover photo for Michigan Highway 1, as well.
