Over 1,500 of the 3,663 artists in my collection do not have images - picture below shows those with most albums. I have tried refreshing Roon cache so I don’t think that’s the cause.
Whilst most are obscure (and I’m not surprised at no image) I would have thought that others (e.g. Cara Dillon, Copperhead) would have images. Anyway, I started finding and adding images, resizing them first before adding to Roon. It’s a long-winded process - I have done 269 so far with 1,313 to go!
What would make it much easier would be the ability to point - within settings - to a folder which has artist images. Roon would then add the images (using the artist name to match to the image (jpg) file and automatically add them.
