Thank you for your quick answer!
You're welcome!
One last question: can I go with the home button ( in the pro version) back to any page I want of my site or only to the index?
You can point the Back Button towards any URL you like via the backButtonUrl configuration option (the URL does not even need to be within your site).
The path for the backButtonUrl can be relative (to the web page containing the gallery's embedding code) or absolute (in the form 'http://www.example.com/gallery/index.html')
And with the galleries I use now it is possible to insert more than one button, so that you can go back to different pages of my site or is that not possible?
The Back Button is the easiest way to include a link in a gallery (and the only dedicated feature available to do so).
You can, however, use the Gallery Title as a link and you can also include links in image titles and captions using HTML formatting as noted in these FAQs:
How do I add HTML formatting to image captions and titles?
How do I add HTML formatting to the Gallery Title or Back Button?
It sounds like you might want to have links alongside the gallery (pointing towards other pages within your site).
If so, then you might like to take a look at another of our products, Showkase, which allows you to create a complete portfolio website including Juicebox gallery pages and non-gallery pages (where you can add whatever content you like). Every Showkase site features an automatically-generated navigation menu (with links to all pages within the site).
Showkase is a PHP web application which in installed on your web server and whose interface is accessed via a web browser.
Showkase has full support for Juicebox-Pro and the galleries can be created within the application itself via its interface (or created with JuiceboxBuilder 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.
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) 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).
I hope you find this information useful.
