Maintain a catalog of image content

Web designers have a lot to keep track of with respect to images. Publishing Web images involves both the visible properties of an image and its nonvisible properties—such as alt-text and long descriptions. In order to ensure quality and consistency, keep some sort of catalog of image content. When image cataloging is part of the Web design process, the task of composing alternate text becomes a deliberate part of providing image content. When an image is used in multiple locations, the catalog can be the source for the alternate text.
