I've used iStockPhoto for some of my friend's web sites. Their photos have gotten better over the years, and there's more variety. They've increased the prices -- now you need to buy "credits" ($10 gets you 10 credits) which you must spend wihtin 1 year. Small pictures I get usually cost 1-5 credits ($1-$5). But I worry if I don't used up all my credits in time (or forget), I'll have wasted part of my money.
