Dreamstime has been around for a while, but I do not hear a lot of people talking about it. One reason may be their Royalty Free license has more options than most and the image price can vary quite a bit based on the options (which seem confusing and easier to find images elsewhere without the confusion). But the images are great, with lots of unique photography for topics not found on other sites.
