Hi Mac, I don't think I understand.

When I load Eric's code, the ASCII image is not exported.  The png  
file is created on the fly and then *replaces* the ASCII drawing in  
HTML document - works beautifully for me.

In fact so beautifully that I am asking the author of ditaa if we can  
keep a copy in the contrib directory, so that all of this will work  
out of the box......
