You can create an iTunes account without credit card info if you buy an iTunes gift card. There's a link (not incredibly obvious) on the iTunes store for you to redeem the gift card by entering the code on the back of the card. Once you have done this, when you go to set up an iTunes account you can skip the credit card part. The drawback of this method is that you have to buy the iTunes gift card, the cheapest of which I think is $15. This will mean you can buy 15 songs, though, in addition to getting all the album artwork, and at least you don't have to give out your credit card info.
