Paul,
I know that VinylStudio automatically downsizes album cover art to 600 X 600 to reduce file size. Recently, I've been taking pictures of albums and then saving them as 1200 X 1200 image files.
I can change the cover art after VinylStudio has saved the album, but was wondering if you could provide a way to make the maximum cover art size either selectable or at least with a larger maximum file size.
