Photo Gallery Improvements

[jordyarms]

Extends: Issue #7
From: PR #8 (review)

Looks great and appears to perform really well!

Nice to haves - can be added now or in future updates if desired:

• Photographer credit?
• Some delineation / indication between day 1 and 2 photos?
• Is there some way to cache the image processing in the repo itself? It took 52 seconds to process on my first run.

To Do Items:

• Photographer credit: https://www.jaxvu.com
• image processing run optimization – caching? (relevant if work on the site continues – low value if we're at the end of development)
• day 1 and day 2 photo distinction (nice to have)
