In regards to adding album art...Whats the difference between adding it manually (d/l pix and manually adding it) and using a third party program like cover sutra or a widget (amazon art or album art widget)? It seems they both work equally well, but when I add my art with the widgets, it takes up more space on my macbook (anywhere b/w 2-15 megs) while manually doing it takes up the space of only the d/l'ed picture (2 megs or less). Whats better and whats the difference b/w: manual & third party? Why does it take more space using a third party? Are there any other methods that are better?
