iStockPhoto has once again reduced the number of images that photographers and artists can upload. Instead of the daily limit, there's now a weekly limit based on the number of downloads that a photographer/artist has:
Grey/Newbie: 30 uploads per week
Bronze: 40 uploads per week
Silver: 50 uploads per week
Gold: 60 uploads per week
Diamond: 100 uploads per week
Once again, it seems that people who have been with iStockPhoto since the beginning are being rewarded for their loyalty. Some can now upload more than 3 times as many images as new contributors.
