This is an important feature for organising images.
For cover page, although there is a property (under hidden objects flag) of “cover image or color”, it displays a meaningless (perhaps encrypted code) of the cover image / colour, which prevents users to reuse the image else where or figure out the media used from an All object Query.
If we have backlinks for images, we could identify and access the image.
Use case:
I am trying to reorganise some older objects and move their cover page to canvas (and refresh these objects with newer cover image), but since I don’t know the image’s name, I couldn’t search for it, to link, or redisplay/reuse or transclude the image.
