Techniques for Attaching Multi-Media Content

External Images, Sounds, and Animations

You may want to have an image open as a separate document when a user activates a link on either a word or a smaller, inline version of the image included in your document. This is called an external image, and it is useful if you do not wish to slow down the loading of the main document with large inline images. 
To include a reference to an external image, enter: 

<A href="MyImage.gif">link anchor</A>

You can also use a smaller image as a link to a larger image. Enter: 

<A href="LargerImage.gif"><IMG src="SmallImage.gif"></A>

The reader sees the SmallImage.gif image and clicks on it to open the LargerImage.gif file. 

Use the same syntax for links to external animations and sounds. The only difference is the file extension of the linked file. For example,  <A href="AdamsRib.mov">link anchor</A>  specifies a link to a QuickTime movie.
Some common file types and their extensions are: 

File Type Extentions

Keep in mind your intended audience and their access to software. Most UNIX workstations, for instance, cannot view QuickTime movies.
