Patch built on top of jlama's most recent patch, which improves upon the basepath functionality for implementations using local image files. In particular, it tries removing the query string from the end of the path in order to try to find the local file, and applies the basepath-based file search to files specified in locations other than the src attribute of tags. Has been tested with and successfully loads images specified by the html background attribute (i.e.
<td background="path/to/image" ... >
) and background images specified within CSS (i.e.background: url(path/to/image)
), and probably will work for images specified by other standard means as well.
