The Image Gallery content block can be used to display images in a navigable "lightbox" type slideshow.
In "Image Gallery Settings," in addition to the other content blocks, you can configure the following:
- Masonry - By default, the image gallery will display as a grid of square thumbnail images. Selecting masonry will maintain the image's original aspect ratio and display the images in a top-down then right masonry-like pattern.
This is a multiple image upload field where you will be asked to fill in a required accessible alternative text value and an optional global caption for each image. You can drag and drop the order of the images after insert. The display order of the images depends on the default (left to right, wrap) or masonry (top-down, wrap) style selection.
For details, see the Image Specifications documentation.
