First of thanks for the great help one can find in these forums.

I did change the order on my product page but I have a few issues.

1. Additional images
Here:
http://www.petitplat.fr/zencart/inde...roducts_id=241

The additional images show up as a column, and I'd like to have them in a grid way.

Which weirdly is the case here:
http://www.petitplat.fr/zencart/inde...roducts_id=251

But if possible with less "space" between the pictures.

2. Add to Cart button emplacement

When I have attributes, it looks good:
http://www.petitplat.fr/zencart/inde...roducts_id=251

But when I don't, the add to cart button is beneath the "review" and "tell a friend". which is a little odd:
http://www.petitplat.fr/zencart/inde...roducts_id=247

(if it's too complicated I can indeed add a text attribute which will solve the problem)

Thanks in advance!
