If you've ever flicked through one of those image-bank CDs that come free with computer magazines you'll be familiar with a thumbnail indexing system. Some image-editing software now includes thumbnail or slideshow viewing but if you're going to store a large number of images it's sensible to go for a dedicated cataloguing program. The best of these are Pixology Piccolo, K5 Photo from Keypix and Extenss Portfolio.
Offered in both single-user and network form, Portfolio is a scalable, flexible system favoured by some of the largest image databanks such as Corbis and Getty PhotoDisc. It also can be used to collate sound and text files which makes it a particularly versatile cataloguing tool for teachers.
