If you are feeling brave and want to try to find them here is how to do it:
Go to http://www.everybodysmile.biz/photosynergy/ then click on "Click here to find your events", then go to Munstead 21st March Show Jumping, then go to page 6 and ours are pictures from 0841-0845 (I like the 0842 and 0843 :). The 0844 is weird as his take off point was just at the bottom of that oxer :(
XC Pictures: as above but go to Munstead 31st March XC, then go to page 6, our are images starting in the first raw (last one on the right): 0484 to 0487.
I wish it was possible to link to them but it isn't :(
