Although that cleared up pretty quickly by the time I was past Alperton:
Not had any joy getting ShoZu or similar installed to quickly post photos from the phone. I suspect Vodafone crippled it intentionally to try and get you to use their "Live! Studio" crud. Hence the lo-res photos. Can still download full photos via USB... but don't have a cable at work.
Annoyingly, the towpath is being dug up/resurfaced or for some other reason blocked just around North Action. And the A40 cycle paths are blocked due to the bridge works. And then White City and Shepherd's Bush are both undergoing work that means the cycle lanes are blocked... might just take the bike back home on the tube: because the Paddington to Greenford mainline is down too. I think my timing of when to start cycling again sucks :|
