Patches Rails 3 to automatically look for images in a folder corresponding to the current locale (under 'images', ie: '/images/en'), and falling back first to the folder of the default_locale, and then to the main images folder ('/images') if the image was not found in the locale folder. Put any localized images in their corresponding folders ('/images/en', '/images/es', etc.) and any non-localized images in '/images'. No need to specify anything special in the view, just use image_tag as usual.
