Don't know about the time thing Chris.

At the moment, I'm doing the galleries - all in one go. I'm in 1day 6hours, just under 100,000 files, 3.36 GBytes and one error so I hope I'm getting something that I can actually access! No idea how much longer it has to go but at 50000 B/s it's pretty damned slow. Don't know if B/s is bits or Bytes/sec. Sure hope it's Bytes.

Pity there was no time to experiment with the settings before starting off. I've a feeling that the depth to which links are follwed has a very significant impact on the process so I'm off to do some testing before the galleries are complete or my router starts to smoke or my ISP pulls the plug...
