Trouble is sound is essentially a one dimensional time 
waveform, whereas a monochrome image is two dimensional 
spatial distribution.

One solution might be to use stereo sound. Now you can get 
your X axis information in terms of spatial position. Your 
Y information could be encoded as frequency, so that up is 
a higher note, down is a lower note, and finally intensity 
could be simply encoded as loudness.

I guess if you had a very simple picture the sound version 
of the chief blob might be meaningful. But what listening 
to the Mona Lisa would sound like - I know not.
