The HTML version of my "LaTeX for Complete Novices" tutorial uses 
bitmaps to show the example output but where the alt tag isn't 
sufficient to describe the output, the bitmap is linked to a page with a 
more in depth description (e.g. both bitmaps in 
http://theoval.cmp.uea.ac.uk/~nlct/latex/novices/itemize.html). Is this 
the kind of thing that you're thinking about? Any comments to help 
improve the accessibility would be very welcome.
