You can create galleries of images to share with parents via Insight. Each gallery will appear to users as a new menu item, and will need to be enabled via role options. Multiple galleries can be created and you decide who is able to view each gallery via the manage galleries page.
When parents view galleries, the images will play through a slideshow. There are links to move to the next or previous photo, and pause the gallery. All of the images in the gallery will be shown as thumbnails so parents can click on these to view specific images.
