This is a packaged version of lightbox for viewing images on the screen in the popular lightbox design pattern. The plugin includes some view helpers and an automatic install script to make life easier.
You can edit lightbox.js to further tweak these if you wish.
If you install from github with rails 2.1+ it will install the files into your public directory. If you install with another method, you may need to issue a recursive copy command manually.
Also this install script is untested on windows.
In your layout add the following in the head section.
In your template:
<%= load_lightbox %>
For each image that you would like to make a lightbox to
<%= lightbox_to('/images/small.gif', '/images/large.gif', "Tasty image caption")
If you want to have more than one lightbox on a page and have the lightbox operate with a slideshow between images..
<%= lightbox_to('/images/small.gif', '/images/large.gif', "Tasty image caption", "group_name")
Where group name needs to be the same for all images in the slideshow.
