How to create one large css sprite image with flags of all world countries, and the set of corresponding css styles for each country?

We have a website where we need to use country flag images when displaying things like "list of countries", "country in the user profile", etc. At this moment, we use independent images for each country. So when we need to show a list of 200+ countries, the delay caused by loading images is very noticeable. I think the page performance / response time could be improved if we would use just one large css sprite image with all the country flag
