It is now possible to use a Wikipedia and Panoramio layer in your own Maps. You can use the layers by inserting the following codes.
map.addOverlay(new GLayer("com.panoramio.all")); map.addOverlay(new GLayer("org.wikipedia.nl"));
There is an option to use a localized version of the Wikipedia layer by changing the domain.
