Re: Screen Readers and Complex Graphics

[Gregory P Sweet <gps03 -at- health -dot- state -dot- ny -dot- us>]

Patricia,

Ohh! Ohh! I just learned this at a NYS Forum accesibility class!

You want to use the longdesc attribute for the IMG tag. It allows you to
link to a flat text file that is accessible by screen readers. It allows
for unlimted text to describe what's going on in an image.

e.g., <IMG title="foo jpg" alt="A digram of typical network architecture
for foo application" longdesc="foo_long_desc.txt" src="foo.jpg">

Cheers!

Greg
