CSS and screen readers

Hello

I am striving to create more accessible websites. So I am going to stop 
using tables for layout. I have created a three column layout using CSS for 
positioning, the columns at the sides containing images. Without the style 
sheet the content is logically organised, with the images and layout 
separated from the content.

When I have viewed this using "Supernova Reader Magnifier - Award-winning 
magnification, speech & Braille for Windows" (which I have been told is 
used by a lot of libraries) the voice reader reads across the whole page as 
it appears on the screen, so the alt tags for the images get mixed up with 
reading out the text in the main column. Which doesn't seem much of an 
advance on using tables?

Is there someway that I can get the voice reader to read the content 
without the style-sheet? Should I be using an aural style sheet?

I would be very grateful for any comments, and or suggestions about where I 
could find out more about this issue.

Many thanks
Madeleine
