Solved my own problem. It turns out that the absurd resolution restriction has been removed (it will now go to 12MP - coincidentally the same as the X100...) but an absurd default remains. Change the setting and it can see the photos. Simples.
My 'work' photos are at http://www.flickr.com/photos/trackcycling for now but will
be moving to my new blogs at http://swarbrick.com (cycling) and http://guyswarbrick.com (not)
The 'fun' stuff - road cycling and, more frequently, not cycling - is at http://www.flickr.com/photos/swarbrick
I'm gswarbrick and trackcycling on twitter
I think that's everything!
