# This is how I leveraged twitter bootstrap modals http://twitter.github.com/bootstrap/javascript.html#modals
# in Rails 3.2 with bootstrap-sass working. This is HAML syntax. With Twitter Bootstrap > 2.0.3.1. The pictures are
# pulled from Google Picasa Web Albums and are the url to the thumbnail image. This also explains the .gsub in the 
# helper as I swap the thumbnail out out with a larger image. This will give you a thumbnail array similar to the 
# "more examples" one on this page http://twitter.github.com/bootstrap/components.html#thumbnails

# in your helper file.
