A fair amount of this months news comes from istockphoto, the most important being their lunch of photo+ for their non-exclusive members. The system allows contributors to 'promote' a portion of their portfolio (percentage depends on acceptance ratio) to be offered at the same prices as exclusive photographers standard images. It seems at present there is no best match or search engine boost associated with opting photos into photo+ (regardless of discussion on weather this is in istocks best interest to farm high priced sales). Photos are locked into photos plus for 6 months (not sure why). I'm a little hazy on commission rates also with some sellers reporting images sold for 66% more revenue (you would expect 50 or less if the photo was being sold at the same commission rate).
