This is a instructable describing how to cumbersomely export your existing iTunes album art and arrange all the covers into a huge grid, leaving you with a gigantic, colourful and vibrant mishmash of popular culture ready for printing and, maybe later, your wall!
I decided I wanted to do this a couple of nights ago and now I’ve come up with a method, it’s not really complicated but can be rather time-consuming depending on how large your library is.
I have around 800 albums with attached album art and it took at least an hour, granted most of that time is spent watching your computer doing all the work for you.
The process requires you to download some free applications (links supplied) and you also need a new-ish version of Photoshop (I use CS3) although I’ll show you an alternate way of getting basically the same results with Google’s free digital photo organizer, Picasa2.
