Here's one of the screenshots from the BBC iPlayer. You can get the image for any of the shows featured there by modifying the address below with the correct item code in the filename. In this case it's 'b00n15l8', but when you click on any other show that number will be different and should be changed accordingly.

I realise this info won't be of much use to most people, but it's handy all the same.
