LightPress Lightbox is a popular, very lightweight lightbox plugin for WordPress. It is active 40,000 websites. After activation, settings will appear under ‘Lightbox’ on your website’s main admin menu, and images and galleries will open in a nice lightbox.
To make images open in the lightbox, you need to set images to “Link To:” media file. For image blocks, this setting is on the toolbar at the top of the block. For galleries, this setting is on the sidebar by other block options.
