Very nice!
I have one suggestion that you might like…
In your Market Theme's images folder (/imgs/), there are two shopping cart icon graphics. (cart.gif and cart-dark.gif)
"cart-dark.gif" is thrown in there to use with dark website backgrounds, so I'd recommend using that.
All you have to do, is switch out those two graphics. There are two ways to do this:
1. Edit your "header.php" file (around line #88) to call the "cart-dark.gif" image, rather than the "cart.gif" image.
-or-
2. You can simply rename the image file "cart-dark.gif" to "cart.gif" and overwrite the graphic.
This is just a subtle change, but I thought you might benefit.
Good job on the site.
Would you mind if we used some of your comments in our upcoming member testimonials area?
