It’s been awhile since I signed dup as a photographer at iStockPhoto. It took a few months more before I started to build my portfolio, but I’ve almost made it a habit to add a few images regularly to my portfolio, and sales are picking up. A year ago I made a sale every month; in the spring I went to weekly sales; and not (almost) daily sales the past month. While it doesn’t pay any bills, it sure is nice to see strangers actually paying for the right to use them.
