I'm interested in looking up some of the artworks found on Magic: The Gathering cards. Is there a website where card art is featured, preferably in higher definition than on the various card search engines? I am highly interested in artworks from the Coldsnap expansion, where you seem to find little in terms of artworks.
Wizards releases some of the card arts in larger size in their wallpaper gallery, however I didn't see any Coldsnap art in there.
Other than that I would suggest seeing if the artist for the card you are looking for has their own website, since the artists do retain some right to their artwork. For example John Avon and Steve Arglye are both artists for Magic that have some of the artwork they've done at higher resolutions.
Doing a google search brings up http://www.artofmtg.com and it does look like they have a Coldsnap gallery. It doesn't tend to have all card images, but it does have a good number.
