istockphoto, once one of the best sites for royalty-free stock images for poor designers like me, has gone over to a pay system: "Members can now download from a database of images, audio, Flash and more for 25 cents per download - new users start with 5 download credits. Download credits are accumulated either by depositing money into your iStock account or from download earnings. iStock uses $.20 from each download to cover its bandwidth costs, and $.05 (five cents) is returned to the member who uploaded the file. This ensures that regular contributors will always have download credits, and all others can download photos for only $.25 each."
