Additional Album art using embedded album art (or all in the folder)

[Minimtc]

A feature request to enable renderer display of additional album art.
I noticed that where multiple images are embedded as album art, MinimServer will select the image tagged as "Cover (front)", so there must be processing already that isolates the one image for presentation to the renderer as the cover art.

Roon has a different feature, which I am seeking the equivalent (or better) within Minimserver. Any images stored in the same folder as an album, are presented within Roon, enabling cycling from left to right to show them one by one within the Roon app. Roon does not allow zoom-in to an image; but Jplay does, which I quite like, in particular to view the text say on the album cover.

** Would it be possible to push further images to the renderer?
Either following the Roon example, which would be great to enable any image to be displayed in the renderer, perhaps as per Roon, which relies on the folder where the album music files are stored.
Or alternatively using the image meta tags from the images embedded in the file itself? The within file option, may be easier to code and allows flexibility based on further configuration based on metatags of the images (Front, Back, Booklet and other tags) - See sample image of tags from Fleetwood Mac - Rumours. Jaikoz.
*****
In particular, it would be very useful to have the "Cover (Back)" available, perhaps to be displayed along with the album front cover art, that could be accessed via a key press, as an alternative view when in the single album renderer view?
The back cover is particularly useful, as it provides confirmation of the track information on that particular edition of an album.

I understand others have posted and a previous response has been to embed additional images in a PDF as a booklet, but this would take a lot of time to arrange across all albums, and besides, I am using the PDF feature to point to a URL, that searches Musicbrainz to bring up the web page for the artist, so the PDF booklet route, is less favourable.[attachment=3560]

MinimServer is a UPnP server, so it uses the UPnP protocol to send images to the control point (not the renderer). Each image must be associated with a library item (audio file, album, artist, etc.) The UPnP protocol doesn't allow sending mutiple different images for the same library item. Roon uses its own proprietary protocol, so it can do things that aren't supported by UPnP.

The UPnP protocol does support libraries containing images (photos) and videos but this is different from associating images with audio files and isn't supported by MinimServer.
