Hi @Sangwoo_Han
Welcome to our Roon community and thank you for your question. It sounds like you’re doing everything correctly.
If you choose the artist photo icon (see screenshot below) you should see a photo of the performer.
However, if there isn’t an image for the artist in Roon then the artist image icon won’t be present. This could be the cause for what you’re experiencing.
For instance, we don’t have an artist image for Johnny Ace in Roon, so the artist image icon doesn’t appear on that now playing page.
In these cases we can use your help! Our new Art Director feature allows our customers to add, position, and crop artist images in Roon. You can also vote on submissions from others in our Community.
