....if you select the Wikipedia layer from the panel bottom left of your Google Earth window. (Click the "+" by "Geographic Web", then tick "Wikipedia").
But it's all a mystery to me as to what Goo Glearth decides to pick up and what it doesn't. Harringay and many of the "towns" around were all given place-names on the standard layer - many in the wrong place. Now most of the London placenames have disappeared. Oh, except a marker for the London Borough of Haringey which they have somewhere near the Emirates Stadium.
By mid December, if you also tick your Panoramio layer on Goo Glearth, there should be a whole bunch of Harringay pictures showing up too.
Yeah, ok, so I've got too much time on my hands right now.
