iTunes may need some time before it will display your new Covers.
You can force iTunes to immediately update the iTunes library with your new covers by simply playing the song in iTunes. In many cases it is sufficient to just select the album in the grid-view of iTunes, to force iTunes looking for new covers.
Additionally users can scroll through their music using Cover Flow within iTunes. This may also help force iTunes to see the Album Art.
You can find this information and many more tipps in the manual
