With Juicebox-Lite (and Juicebox-Pro), you can create as many individual galleries as you like.
You can display each gallery on a web page of its own (via the 'index.html' page generated by JuiceboxBuilder) or embed each gallery into a web page alongside other content following the instructions in the Embedding Guide.

However, if you would like to link them all together (for example, with a navigation menu), then you would need to do so manually. perhaps following the instructions in the Embedding Multiple Galleries support section.
You can copy and modify the online examples if you like but please note that knowledge of HTML (and most likely some CSS and JavaScript, too) would be required. You can check out the code of the examples by viewing the source of the sample web pages in your browser.

Alternatively, you might like to try the template I provided in this forum thread.
It is a quick and easy way (a single HTML page in addition to your galleries) to link together a few galleries (with very little coding required) and it might be an easier solution than modifying the examples in the Embedding Multiple Galleries support section.

However, if you are looking for a fully automated and customizable method of creating and displaying multiple galleries, then you might like to take a look at another one of our products - Showkase.

Showkase is a PHP web application (installed on your web server rather than your computer) which allows you to create a complete portfolio web site (integrating multiple galleries) online.
Showkase has full support for Juicebox-Pro and the galleries can be created within the application itself in a web browser interface (or created with JuiceboxBuilder-Pro and imported).

You can create Gallery Index pages and have as many galleries listed on each Gallery Index page as you wish.
Each gallery is represented by a thumbnail image with the gallery title displayed below and the gallery is opened when the user clicks on the image.
Demo sites created with Showkase can be found here.
... and a sample Gallery Index page can be found here.

Please note that although there is no limit to the number of galleries you can have within a Showkase site, Showkase supports only one gallery per web page.

Showkase can also create non-gallery pages (About, Basic and Contact pages) where you can add information about yourself (or any other content you like).
All of this is done automatically within the Showkase interface without the need for any manual coding at all.
You can take a look around the Showkase interface by logging into the 'Live Demo Admin'.

Showkase can be purchased as Showkase-Standard (which comes with Juicebox-Lite, the free version) or Showkase-Pro (which comes with Juicebox-Pro).
The only difference between Showkase-Standard and Showkase-Pro is the bundled viewer (Juicebox-Lite vs Juicebox-Pro).

Key differences between Juicebox-Lite and Juicebox-Pro are:

• Juicebox-Lite has a limit of 50 images per gallery. Juicebox-Pro has no image limit for local gallery and a limit of 500 images for a Flickr-sourced gallery (limit imposed by Flickr).

• Juicebox-Pro has many more gallery configuration options than Juicebox-Lite. Check out the Config Options page. Juicebox-Pro supports all options on the page whereas Juicebox-Lite supports only the Lite options.

Please check out the other Lite vs Pro differences on our Download Page.

I realize that there is a lot to digest in the information and links above but I hope that it is helpful.
Please let me know if you have any further questions and I'll do my best to answer them for you.
Thank you.
