Not a lot of sales on this site which as of Nov 2016 appears to be stagnant.
Back in 1999/2000 there was a site called zden which allowed users to sell (and store) their digital work for z's which could be converted into money (that was the plan), the site was ahead of its time and it folded (perhaps it was too good to be true that you could just store your files for free) - I'm not sure of the details but I had some of my work uploaded there. You could upload pretty much what you wanted and set your price, and I mention it here because cutcaster reminds me of it. They seem to have formed a space where designers/creators/photographers and videographers etc. can show and sell their work, it's more than just "search for images of XXX"
At the moment I'm monitoring the results from cutcaster and as such recommend you focus your efforts on the sites in my top sites list in the microstockinsider recommended post. If you have some spare time (lucky you!!!) and some premium photography that you want to charge more than a couple of dollars for then this site might be worth an experiment.
2008: A very neat feature of cutcaster is that it includes an optional dynamic pricing algorithm which can vary the prices of your images or video to increase sales. It will be interesting to see how well this gets over the old "price too high and they won't buy, price too low and they will think you are selling rubbish" problem. (2015 edit - clearly it didn't work) sites like Dreamstime have implemented price tiering, this type of feature can only be a good thing for contributors as it increases the return on 'in demand' images while still allowing sales of less popular images for low cost to users who do not want to pay the premium. Buyers who were attracted to low cost images may err for the more expensive image if they like it enough (a perceived sense of increased quality), especially if the difference is only a few dollars.
Very slow sales as of 2015 at cutcaster and now in 2016 uploads have not been working for at least 6 months. I recommend you do not upload (well at time of writing you simply cant!) to Cutcaster.
