People have been generous with adding their images to the pool. It may not be the largest island group on Flickr, but it may be the most diverse: it already includes islands from 125 countries and separately administered territories, from Albania to Zimbabwe. I am particularly pleased to have Andorra — a landlocked mountain country — and Libya, which has almost no islands. These are the countries:

If you have any island pictures from Afghanistan, Bhutan, Bosnia, Central African Republic, Jordan, Kosovo, Lesotho, Liechtenstein, Luxembourg, Moldova, North Korea, San Marino, Somalia, Tajikistan, or Uzbekistan, please let me know.

That is a tough one, as my estimate of the number of inhabited islands in the world is 11,000, including all sea, river, and lake islands. There is no central list of any category of them.

Two places that will capture the major ones — especially large sea islands — are:

• The CIA World Factbook for all island countries
• World Island Info’s list of most populous islands
