Hi Isaac, if you check the HTML output you will see that it contains something
like:

<img src="images/figu-Beginners_Guide-Visual_Web_Tools-Visual_Page_Editor.png"
alt="The Visual Page Editor, showing both the source and a visual preview
simultaneously." width="444">

The IMG alt tag is set correctly. If you disable images this alt text will be
displayed. If you use a reader for the blind this text will be spoken.

The display you are talking about is not alt text, it is tool tip text. The
tool tip text would need to be set by adding another attribute, title, to the
IMG output. Basically the display you are talking about would require
duplicating the content of alt in the title attribute.

There is nothing in the DocBook XSL to set the title attribute in the IMG tag,
so we'd have to add this functionality.

Cheers, Jeff.
