what are the ratings for
Ratings are for entertainment purposes only. If a member wants to give you a rating along with a comment to show how they feel about your work this is an option they can use. The ratings are from 1 to 5 stars with 5 being the best on down to 1. Then once at least 2 or more ratings are made on one of your images the system calculates the "average" rating for that image and it will appear on the statistics box for that image.
Hope this helps.
