Serviio

I have 3 TV's in my home: 2-Smart TV and 1-GeneralTV with Mini M8S II TV SmartBox with Kodi 18.4 (all connected to LAN). Also I have Windows Serviio DLNA server in my LAN. While 2 Smart TV show my video and photo from Serviio very well, TV with Kodi don't show pictures - only Video .

I read posts with explanation why Kodi don't share library with pictures when it works as DLNA Server. But why it can't do it as DLNA client? The old Kodi 16.1 can do it!
May be detaching DLNA-client in separated feature will solve problem?

I have Kodi 18.4 on my Nvidia Shield, and get both images and metadata from Serviio. MrMC gets images but no metadata. I don't believe I've changed anything in the settings to get the images, but there are so many settings perhaps there is something I changed. Make sure you switch the settings to Expert mode to see all the possible settings.

Although let me ask a clarification question. Do you mean you're not getting the cover art for your movies/series or do you mean that you're not getting thumbnail images of your pictures (and nothing to do with videos)?
