Allow pinned display of reference image for scene/character/location#1000

When pinning the notes for a scene, character, or location to the right sidebar, it would be great if you had the option of selecting whether the textual description of said element or an image for it is displayed in the tile (like Scrivener does with the inspector). Sometimes having the visual reference ready and available while writing is much more helpful for capturing the mood. Right now, to view any image, you need to click the images icon to open them. Understandably, only one image could be displayed in the sidebar at a time, but having it be an option to select one of many images for an element might be used for that purpose seems viable.
