Users can now open images from the page content in a lightbox. While hovering an image, a toolbar will appear with options for opening the image in lightbox mode or to download it. The lightbox will display the image along with some information about it, depending if it's attached to a wiki page or it's an external one, and with some actions like download, toggle the browser full screen mode or start a carousel play of all images found in the page content. You can toggle the visibility of the image caption and action buttons by clicking on the image.

The lightbox feature is disabled by default and can be enabled from the Administration, Look & Feel -> Lightbox section. Checkout the documentation for more information.
