iTunes won't let me add album artwork.
So I have added a homemade album to iTunes, and I have never really had too much trouble with it before, but it's not showing the album artwork I'm adding. When I click on the album or select all the songs and then go into 'Get Info,' I can go into my computer and choose what I want for my artwork. It is just a normal picture file, and when I click open file, it shows up in the preview, but when I click the okay button to save to the songs/album, it doesn't update. I've restarted iTunes and tried again, and still nothing. No error message or 'cannot be uploaded' or anything.
