+
+The `insertGalleryContent` method allows you to add media to media galleries across various pages of Dealer.com sites. The only currently supported target is `vehicle-media`, which will insert media into the media carousel of Vehicle Details Pages.
+
+`objOrArray` is an array of objects describing the media to be inserted. If you have a single image, you can pass a single object instead. Each object has a `type` field to specify the type of media to be inserted. The only currently supported media type is `image`.
+
+The `image` type supports the following additional attributes:
+
+Name | Description
+-------------- | --------------
+`position` | Where to insert the image. `primary` is used for content that should be displayed to the user as soon as it loads -- as long as the user has not explicitly performed an action to look at pre-existing media. `secondary` is used for content that should be displayed soon, but not replace the pre-existing main image. `last` is used to append content to the end of an existing gallery.
+`src` | HTTPS url to the image to be inserted.
+`thumbnail` | HTTPS url to a thumbnail of the image to be inserted. For performance, it is ideal to provide a low resolution thumbnail that can be used for a preview of the inserted image, however, `src` will be used if `thumbnail` is not provided.
