Lightbox Settings

• Enable Lightbox (lightbox) — opens the full image when a thumbnail is clicked. Default: Yes. Disable it when custom items should behave as links.
• Opening Effect (lightbox_effect) — Zoom, Fade, Slide Up, or None. Default: Zoom. Shown only when the lightbox is enabled.
• Overlay Colour (overlay_color) — colour and opacity behind the viewer. Default: rgba(3, 7, 18, 0.94).
• Lightbox Caption (show_lightbox_caption) — displays the title and caption beneath the full image. Default: Yes.
• Download Button (show_download) — provides a direct download action for the current original image. Default: No.

The viewer includes previous/next controls, image counter, backdrop and Escape closing, Left/Right keyboard navigation, focus trapping, and focus restoration. When lightbox is disabled, a custom item’s Optional Link becomes its click destination.
