When i add album art to my Ipod touch, when it is playing the song the art is black.?

so i went through and added the album art to a bunch of albums that i have on my touch. then wehn i turn it on, only 10% of the picture is showing at the top and the rest is just black. this happens for all the artwork that i manually put on. However when i get a song that comes with artwork it shows up perfectly fine. Does anyone know how to change it so when i add the artwork it shows it?When i add album art to my Ipod touch, when it is playing the song the art is black.?Yes that happens if you manually do it (on the iPod touch's file in iTunes). If you make that same edit to the music file in the iTunes library then sync or drag/drop that into the iPod touch it would work.
