As things stand I have 2706 artists and 567 albums in my library for which Roon has no artwork.
Please could consideration be given to adding the ability to open a browser based google search that takes the tedium out of having to manually search for same, much like the current Wikipedia, Facebook etc. links only this one opens a pre-populated google image search in the user’s browser? A simple right-click or long press on a blank cover tile can bring up a Search Google option.
Even better, once a user has filled in an image gap … use it improve the Roon’s metadata.
I’m sure the Roon dev are aware of crowdsourcing techniques that could be employed.
Copyright issues alert! 
Nonsense, Roon isn’t doing anything but facilitating a search of what’s already publicly available via any browser.
My comment was about the crowdsourcing that Carl alluded to. Sure, I’m sure we all have grabbed images for personal use, but to have a public shareable resource would require some attention to copyright issues, unless you want to condone piracy…
skip the crowd sourcing then if necessary, sounds like can of worms that cannot be untangled.
Can roon not add more image providers??
I find Plex better at this…and that’s a free app
+1 from me, a great idea.
