This is a common card game, and it could probably be implemented without having to use card images.

You could just display the numbers.

For example:

Dealer Score: 17

Your Score: 15

Hit / Stand etc.

I could definitely do that as long as there is no images...Someone would have to refresh me on the rules again

As for images, if you could incorporate them but don't want to due to not having the images, you could use these:

They are GPL so there's no copyright issues. I could convert them to PNG as well as resize them for you if you're interested.

Now a blackjack plugin... Man i would love to see that. Really. Love to see that.
