Not blocking, but could you make Sponsors & Supporters title case like here?

I would like to add Atomic Maps here. I'll do that in another PR.

Nice website BTW!

Should we host the sponsor images within the repo?

Hi @jamesfisher-geo. I will make the change on the punctuation. Definitely add Atomic Maps! We should probably host the sponsor images in the repo. Thank you
