I was trying to upload a photo for the Rachmaninoff International Orchestra. After Copying the Image, I pasted to Valence but nothing happened: no error (e.g. must be > 500 pixels), nothing. So I saved the JPG file and tried again. Here’s what happened:
I then tried uploading (as a test) another image that I knew Roon would accept (I had added it earlier). Same result.
It’s quite possible this is user error. If so, please advise. FYI.
