Here is a company making it easier to buy images. Photos, illustrations, videos and audio tracks can be added directly to a shopping cart after which you can pay by credit card and then download your pick. With iStockphoto you can pay in US$ and the company’s own credits. There a millions of files starting from as low as two or three dollars per file. iStockphoto is a subsidiary of Getty Images. The only drawback one can see is that most ad agencies do not give art directors a company credit card. Knowing how long agencies take to pay, some may not want to use their personal one!
