I photo is unexpectedly quitting when placing an order.
Try boot into Safe Mode and try again.
What is safe mode?
This is not a problem with iPhoto that will be "fixed" - it is a problem with your system or configuration
Safe Mode is the mode described in the Link TD posted - Do you read it? - basically it disables some non-Apple software to eliminate problems
Actually, I went to the link but there was no explanation.
That's what happens if you read 12 month old threads
