This is an extension for Spree, allowing to show zoomed product images to the customer:
It"s based on Facebox: http://github.com/defunkt/facebox
A lot of code was taken from this project: http://github.com/eliotsykes/spree-zoom-photos
Installation is quite simple (from the spree app root):
script/extension install git://github.com/Antiarchitect/spree-facebox.git
New extra large image size of 1000x1000. So when new image uploaded on server it will have a 1000x1000 size in addition to default sizes, old images will not. I think there is the way to generate extra large size of them through rake (unconfirmed).
Navigation between images from the facebox window
All wishes, suggestions and improvements are welcome!
