The invention is directed to a method and apparatus for constructing a virtual microscope slide. The method encompasses the construction of a data structure by digitally scanning a specimen and acquiring digital image data of a series of digitized adjacent image segments of the specimen. The image segments are useable to provide an overall magnified image of the specimen as well as higher magnification images of selected points on the specimen. The scanned digital image data can be stored and transferred over an Internet or intranet communication channel. A control program is provided for the data structure for viewing the overall magnified image and higher magnification images of selected points on the specimen. The control program allows for the selection of a point on the overall magnified image, and display from the stored digital image data a corresponding higher magnification image of the selected point.
