On Graven Images
Two points on the original question:
(1) The issue in the Ten Commandments has to do with WORSHIP of a graven (or carved or presumably other artfully created) image, as far as I know. Personally, I do not worship nor idolize tarot cards. They are not my god. I don't know of anyone who does worship tarot cards. They are a tool, rather like an illustrated manual or guidebook.
(2) Now, if one believed that the created/printed images were the problem, merely because they were printed images, then that is a far deeper concern. Such people have no business reading books or newspapers, watching television, using a computer, having photos of their family, handling coins or paper money, bonds, stocks, visiting a museum, or even walking down a street where they might be exposed to advertising images! At least since "movable type" was invented, all published material, including the Bible, could be seen as "graven images"...to a literalist.
If such a literal and fundamentalist interpretation were made, then 99.9% of the world's population would stand condemned for breaking that particular commandment in one fashion or another. Myself, I choose not to interpret it anywhere near that broadly, so that I can continue to live in the modern world and not in a cave in some remote location!
Seriously, - jmd makes a very useful distinction between idols and icons.
