In general, this type of royalty-free license grants the right to use any image in any way without additional charges. Sometimes, the license agreement will include additional charges if the image will be printed on an item that will be duplicated and sold. Catalog CDs are also popular because they allow potential buyers to examine a wider range of images. File formats and methods of determining usage rights vary greatly. With low-res catalogs, buyers generally must call and arrange payment and delivery, which can be by credit card and overnight courier or via the Internet.

Most catalog discs come with a preassembled database of the images and an image browser such as Fetch. Better collections tag images with keywords , enabling database searches for the images you need. As I mentioned before, the Internet has given the stock image industry a tremendous boost. The Internet allows cheaper distribution, and the medium itself is driving new business in categories that didn't exist until as recently as a year ago. No company has embraced digital stock delivery as well as PhotoDisc .
