Hypergraphics


Hypergraphics are very similar to hyperlinks in that they are graphics which when clicked will open a file or URL. Many web sites use hypergraphics as a more user friendly alternative to hypertext for example when creating a table of contents. However it is important to remember that some browsers can not display any graphics (or have the graphics feature disabled to enable faster browsing) - therefore it is a good policy to provide a simple hypertext alternative to hypergraphics.

Creating a hypergraphic involves first inserting the graphic, then selecting it with the mouse and then making it "hot" using the Hyperlink button . Using a border around the graphic can help to make it clear that the image is hyperlinked.

Using tables, graphics and hyperlinks it is possible to create many different features on a web page like the navigational buttons shown below.




A similar effect can be created using image maps where parts of the image act as hot spots linking to other web pages. These hot spots can be defined within the HTML code of the page (like the example below) or using remote references on a web server.

More sophisticated features and hypergraphics can be added to a page using scripting languages such as Active X, VB Script and Java. The button below is linked to some simple Active X code which in this case will open Windows Notepad - notice that unlike with the previous examples, the button actually appears to depress!
