I've been running an amateur site at
http://www.justinesbedroom.com/index_ap.html with my wife Justine for over five years and thought maybe I can help with some of your questions.
1 - All photos that we add now are 800x600. We did start adding bigger photos and several members said they were too big. We only add photos that are in focus.
2 - Our photos are made in our home and I think it is good to have stuff left in the photo that shows its really amateur.
3 - We only add hardcore photosets. I think you have to be extremely attractive and sexy to do softcore sets.
4 - I think you should try to update at least three times a week to keep members. We update five days a week with new photosets, movies, erotic stories etc.
5. We add text to photo galleries from Justine saying how she felt etc. while the photos were taken which the members love.
6. I have a custom made gallery generator.
7. Our photos are all different shapes and some are a bit bigger and some a bit smaller but we try to keep to about 800x600
I hope that helps
