Thanks MrC.
So that I understand properly, I have my cover art embedded in the files only. I think I am happy to leave as is at the moment. The resolution is high enough for now.
The more important question is I cannot seem to work out the difference in the cover art page between:
Next to the file as Artist - Album.jpg
Next to the file as Folder.jpg
Do some people want the cover act in the folder as well as embedded. If so, why? And what is the difference between these two folder options above? Thanks!
