Hello everyone!
I have set up a new PC (Windows 11) and re-installed JRiver MC 31. I have found an automatic backup in my old SSD and imported it to a new library. Everything looks OK except cover art. Cover art was stored as Folder.jpg in the same folder as audio files. In Tools -->Options -->File Location-->Cover Art, I have checked "Audio mode: In the same folder as the file (as Folder.jpg). The column "Image File" in the audio files shows "Inside file", but no cover art is shown. I have tried "Rebuild Thumbnail" with no results! What is the problem?
