 You should always call mgGetImages uncached, as it manages caching internally. This makes sure the images on a Gallery resource are in sync with the frontend, without relying on full site cache clears.
 
+## Listing & single image views
+
+The `mgGetImages` snippet by default lists images in a gallery, but it also supports a "single image view" or "detail view". When the page is requested with a `iid` URL parameter (or another parameter defined by the `&singleImageParam` snippet parameter), only the specific image is shown with the `&singleImageTpl`.
+
+The single image view also includes previous and next images, so it can be used for a simple gallery view without any JavaScript solutions. This detail view is also used to render embed codes for videos and iframes for PDFs. The detail view can also be disabled with `&singleImageEnabled`.
+
+The parameter for the rendering of one image in the list is `&imageTpl`, not `&singleImageTpl`.
