ABSTRACT:
A method, program and apparatus for providing access to alternate images in an electronic document are provided. The present invention comprises identifying an initial image to be displayed in an electronic document (typically a web page) and then determining if alternate versions of the image are available for display. If alternate versions of the image are available, they are provided within the same electronic document. The alternate images differ from the initial image in size and resolution, allowing users with visual impairments to access larger, higher resolution images. The user accesses the alternate images by means of a selector displayed within the electronic document. When selected, the alternate image replaces the initial image in the electronic document, and the document is reformatted.
