To open a different lightbox gallery when clicking on buttons in Squarespace, you can use the Lightboxify URLs feature. Here’s how to set it up:

1. Create a Source Gallery

   • Insert a Gallery block or section a page (e.g., /source-gallery)

2. Create the Lightboxify URL

   • Your Lightboxify URL should look like this:
     /source-gallery?lightboxify=true&lightboxify-mode=gallery#gallery-id

3. Set Up the Button

   • Create a Button block & Link the button to the Lightboxify URL you created.

For more detailed instructions, you can visit the How to open a gallery lightbox on button click page.

No, using Lightboxify URLs will not slow down your website. In fact, it can improve performance because the images will be loaded asynchronously. If you have many Lightboxify galleries in your content, it's recommended to put all source galleries on the same page to optimize loading times. This approach helps maintain a fast and responsive user experience while allowing for high-quality image displays.

For more information, you can check the Elevating Dynamic Galleries with Lightboxify URLs page.

Lightboxify URLs support various types of content, including:

• Galleries: You can open seperate lightbox gallery when clicking on different images, buttons or links

• Videos: Lightboxify URLs can be used to create video lightbox galleries. For more details, check out the tutorial on creating video lightbox galleries.

• PDFs: You can embed PDFs in a lightbox using Lightboxify URLs. For guidance, refer to the tutorial on embedding PDFs on Squarespace.

• Alternate Images: You can open alternate images in a lightbox by using Lightboxify URLs. More information can be found in the tutorial on opening alternate lightbox images.

No, each source gallery does not need to be on a separate page. You can put all separate source galleries on a single page and link to them using their Section IDs or Section Anchor IDs (if you use a Gallery section) or Block IDs (if you use a Gallery block). For more details, you can refer to this post about IDs configuration.

No, currently you cannot use Lightboxify URLs in a gallery that has the lightbox feature enabled. If you include Lightboxify URLs in a lightbox-enabled gallery, they will be treated as normal links. For more information, you can refer to the Lightboxify URLs FAQ.
