Graphic Node (http://graphicnode.com/) says its Aperture Themes pack (US$24.99) is now available at the Mac App Store. The 16-piece design add-on for Apple’s Aperture application allows Mac users to explore new ways of conveying their fondness for photography.

Aperture Themes equips users with a collection of designs for laying out photos and pictures and exporting them into Web galleries. Every theme features up to 10 different layouts and can be further customized, resulting in a total of 51 designs.

Eleven of the themes allow the user to display photos in their original sizes, while the remaining five crop images to squares and present them in grids. The Aperture Themes requires Aperture 1.5 or later.
