Wordpress Image Gallery

Hello,

I am using the Atlantica Wordpress theme for my site. The image gallery template is set up as 6 columns of 4 images. I would like to set it up to be fewer images, such as 12 or 16, without the arrows to the left and right to scroll. Here is a URL:

If you can let me know what PHP or CSS to modify, that would be most appreciated. I tried contacting the theme creator, but no response yet.

Thanks,
Colin

In order to be able to help you, you should provide with the downloadable zip formt of the theme. Or you should provide with admin panel of the theme.

It looks like this theme is not free. Are we allowed to get the source and offer suggestions?
