[SOLVED] What's the difference between the Atahualpa and Montezuma themes?

I used to use Atahualpa for a web site for a (very) small business that we own.

I am wanting to prepare a website for an antiques mall. I need a theme that is oriented toward picture display of antiques.

What will Montezuma do that Atahualpa won't do and vice versa?

Thanks.
