Because iTunes embeds album art directly in the files, I'm realizing there's a problem: 1) I've probably added quite a few large (500 kb+) image files as album art without thinking much about it over the years, when such high resolution isn't really important for much of anything. This means I'm using a lot of extra space - maybe even upward of a GB - on needlessly large album art. 2) I don't know of any simple way to check how large the album art embedded in a given MP3 is. If there is a way, you could just go through your music library, find the albums with very large art, and replace it with something more reasonable from the internet. Does anyone know of good solutions to this problem, i.e., reducing the size of album art in your iTunes library?
