Images are also used to provide information in their own right. Certain types of information are better presented graphically than as text. The map, for instance, is something familiar to all of us but while maps are often quite aesthetically pleasing objects (well, I think so anyway), they can also present a huge amount of information. And think about all the different types of maps there are: not just political maps like this one, but geographical maps (showing contours and other land features), stylised underground or metro maps, geological maps, economic maps... Another form of informational image is shown below, a graph. Other examples are blueprints, organisation charts, star charts... the list is frankly endless. Any or all of these could be used to enhance the informational content of your web site, whether or not it's an educational site as such. |
