Here's a tip which might be useful for users with many galleries.
It is possible for multiple galleries to share a single 'jbcore' folder (rather than having an individual 'jbcore' folder for each and every gallery).
In doing so, it would be possible to upgrade every gallery on your website at once (for example, when a new version of Juicebox is released) by just replacing a single 'jbcore' folder (rather then replacing many of them in different locations).

Instructions can be found here: https://www.juicebox.net/support/embedd … ore-folder

Admittedly, if you already have multiple galleries on your website, you'd need to modify the paths to the shared 'juicebox.js' file in each gallery's embedding code but for someone starting out and planning to have many galleries, it might be worth considering.
