When I search for artwork I see very many different sizes available such as, 50x50, 400x400, etc. What is the optimum size to use in iTunes when the artwork will be displayed on an iPod, an iPhone, and an iPad? If I understand correctly, iTunes will resize the artwork to display properly on the devices, but I was wondering if I should look for a "standard" size to add to iTunes that will still look correct whether it is on an iPod or an iPad.

Of course it also depends upon how much space you have on your drive, and how much space on a player if you add them to mp3s or whatever. Perhaps not a huge difference but if you start adding 500k image files to 20,000 tracks then it does add up to a GB or two.
