Downloaded Album artwork is not accepted on itunes
I have a few songs that don't have album artwork. I downloaded the artwork, and when I tried adding it or dropping the artwork on itunes it doesn't accept it. I tried downloading the artwork in jpg, jpeg, and png.
Old artwork that I downloaded previous years will work, but the new artwork wont any hints? I haven't added album artwork in two years, so I do not know if anything changed in the last two years.
