A Gallery Action allows one to display a selection of Actions using the images in the call-to-action of each Action.
This Action uses a standard Tapps' format that builds a higher level Action from a selection of existing Actions.
Tapping the action will trigger the underlying action. Thus, if using a group of Link Actions, each image could link to an item in a store. If using Image Actions, then tapping an image can show a full size image, or do nothing if using the non-clickable option. You can also mix actions.
Optionally, the images will display as 1, 2, 3, or 4 images per row, and additional images will wrap to the next row.
One can also select if the images have square or rounded corners.
A final option controls whether tapping a gallery image opens a subpage showing all the images, or if it directly performs the Action associated with that image.
Reference the Action Formatting and Controls FAQ for a refresher on the controls that are common to Actions.
