About

Rack::Snapshot is a quick way to expand image urls for the popular image sharing services. If you have a URL to a public page for an image on Skitch, Img.ly, Twitpic, Yfrog, Flickr, or Twitgoo, this middleware will embed the direct image URL for you.

Usage

If you're using this in a Rails project, simply configure your environment:

config.gem 'snip-snap', :lib => 'snip_snap', :source => 'http://gemcutter.org'
config.gem 'hpricot'
config.middleware.use "Rack::Snapshot"

If you're using it in a Rack environment, you'll need to make sure that the snip-snap and hpricot gems are installed and then configure the middleware:

use Rack::Snapshot

By default, this will rewrite image tags that contain the class "expand", but you can configure this:

config.middleware.use "Rack::Snapshot", :class_name => 'sekrit'

Expansion of Flickr URLs is supported if you supply your Flickr API key:

config.middleware.use "Rack::Snapshot", :flickr_api_key => 'abc123'

More information is available in the included Gist.
