== Directives when using in powerpoints == 

 Dear David: 
 I have a doubt regarding the license use when using your London picture "Palace of Westminster, London - Feb 2007.jpg" in a Powerpoint. I will set your name under as author, but as the Powerpoint is full of data, I cannot find a suitable place to put the URL with the license. What do you recommend? 

 Thanks,
