fig

Fig is a jQuery plugin that downloads only the first frame of an animated GIF, shows it as a static image, and plays the entire animation on mouse hover. Downloading only the first frame reduces the initial payload and makes pages load faster.

Usage

All GIFs on page must have a "data-src" attribute with the source URL. Do not include an actual "src" or else the browser will download the entire file, thus defeating the purpose of this plugin.

<img data-src="some.gif"/>

Run the plugin:

$('img[data-src]').fig();

You can pass in options to change the overlay colors and text:

$('img[data-src]').fig({
  overlayTextColor: "#ff0000",
  overlayBackgroundColor: "#ffffff",
  overlayText: "Play"
});

Demo

A Sinatra-based demo app has been included.

Run 'bundle install'
Run app with 'bundle exec ruby app.rb'
Visit http://0.0.0.0:4567 or http://0.0.0.0:4567/more?enabled=1

Caveats

Images must be served from the same domain or have CORS headers
Probably will not work on older versions of IE
