Imagine the excruciating
redundancy of hearing ???spacer.gif??? read aloud 30 times in one web page. To tell user
agents that an image has no semantic value to the rest of the document (and to tell screen
readers to ignore the image completely), the tag must contain an empty alt attribute.
For instance:

Multimedia
Although not as common as graphics, multimedia files can present a significantly steeper
road to climb before reaching accessibility nirvana. This category includes Flash files, video
files, audio files, and any other content that is not an image or text. Since multimedia files
range in format, size, and length, their accessibility must be tackled on a per-case basis,
often covering both vision and hearing.
The tag is typically used to load nonstandard content. Placing a QuickTime
movie onto a web page might use code similar to this:
width="300" height="200" ??
codebase="http://www.apple.com/qtactivex/qtplugin.cab">
