The flags of all countries in the world in one sprite

Include 1 css file and have all the worlds' flags on your site. Tell everyone who uses a lot of country flags to use this link, so it will be in everyone's cache!

Example usage:

In the head of your html file:

<link
    rel="stylesheet"
    type="text/css"
    href="http://cloud.github.com/downloads/lafeber/world-flags-sprite/flags32.css"
/>

In the body of your html file:

<ul class="f32">
  <li class="flag ar">Argentina</li>
  <li class="flag au">Australia</li>
  <li class="flag at">Austria</li>
  ...
</ul>

The countries corresponding to the codes can be found at: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2

If a previously visited site uses this same code, the file is already in the cache of the user and doesn't need to be downloaded again. NB: It won't work in https environments. You can download the css files and include them locally instead.

See the cheese wiki: http://www.cheesewiki.com/ for an example

Adding a new flag

These scripts require an old version of numpy and are python2 based, so it's probably best to setup a virtual environment. Run or see make venv

Once you're in your virtual environment, or otherwise have old versions of python stuff installed, run

./add_gloss.py <filename.png>

to add the gloss layer on the top of the flag for a unified look, and then

./add_flag <name> <countrycode> <filename.png>

If countrycode is not going to be a 2 letter code, prefix it with _

to add the file to the appropriate stylesheets and image
