photonic for smugmug showing nothing

Here’s a link to the smugmug folder/galleries I’m trying to use with photonic

PPBMWR Galleries – Brent Berry (smugmug.com)

Thanks. That helped.
Now….
You can find the test page here->PhotonicTest – Pikes Peak BMW Road Riders Assoc (myftpupload.com)

There you’ll find these three galleries. Select one of the galleries and it’s images will load into an overlay, which I like. However, now that I’m in the overlay I cannot find a graceful way to exit the overlay and return to the gallery page, which seems most intuitive to me. Hitting the back arrow on browser returns me to the context that was active prior to the gallery page.

Is there a way to navigate back to the originating gallery page from the overlay?

Much Thanks!
