I wonder which of the photos has been reproduced back to front!
Personally, I wouldn't use a brand new, untested piece of kit for an important shot, especially having had a card fail (cheapo, back when a cheapo 128MB card was about £50!) at an unrepeatable family event. Luckily I was able to get the images off the failed card but have stuck with SanDisk ever since (with no problems. Yet!)
