I didn't meant it this way. The wrapping shell-backend knows the target
format and therefore it should know which file-type for images is the
best for this target format. So it could pass this format (as in "png",
"eps", "gif", ...) in a variable to jade and make it available in the
stylesheet.

The stylesheet has the blank filename (from the SGML source) and the
needed extension (from that variable) of the image-file then. This leads
me to the assumption that this should be enough to build the right
file-name (name + extension) in the stylesheet.

It wouldn't be enough to make sure that the file in the needed format
really exists, yes. But if it exists this could work. I haven't got the
time right now to dig through the stylesheets to see how this could be
done in a driver file and I may well have missed something important,
though.
