img.src.path string
img.src.path Path to HTML/FO image files

## Description

Add a path prefix to the value of the fileref attribute of graphic, inlinegraphic, and imagedata elements. The resulting compound path is used in the output as the value of the src attribute of img (HTML) or external-graphic (FO).

The path given by `img.src.path` could be relative to the directory where the HTML/FO files are created, or it could be an absolute URI. The default value is empty. Be sure to include a trailing slash if needed.

This prefix is not applied to any filerefs that start with "/" or contain "//:".
