600x800 is enough for hosted galleries. The "idea" is to get them to click through to the site where they can see the real images, not to jerk off to the gallery. Having a sample of the full size image on the tour is one thing, having 15 or more on a gallery just does not make sense in the BW department.
I've never understood sponsors that use huge images on their hosted galls. Money to burn on BW I guess. Not knocking it and I've even tried ot for 90 days, but I just have never see it make a difference other then the amount of the server bill each month.
More power to them I guess.
