Well, we made it back with all limbs in one piece.
I've been uploading low res images for family and friends to have a look on pbase, feel free to have a browse :

we still have dial up at home, so I'll post some hi res images tomorrow from the office.
Thanks for the advice on using a dslr in cold temps at altitude, but as you can see it was extremely sunny (25 degrees in the sun). The mountain and cloud shots were taken from Aguille du Midi, which is around 3800m, just 400m shy of the peak on Mont Blanc. Standing next to the fence using both hands to hold the camera when you are dizzy from the altitude and have a 3 year old hanging onto your leg is a strange feeling
