It would be easy enough to have ps2image create the necessary
directory, but another problem is that file.ps will be created as
./dir/file.ps.  This would occur (in texfile.makeimage) before 
ps2image is called, and if htmldirectory isn't ".", then the png file
will be htmldir/dir/file.png.  So both directories ./dir and
htmldir/dir would have to exist.  It would be nice if file.ps were just
./file.ps, but the ps file name is made by TeX based on the image name
dir/file, and I don't know how to (reasonably) strip off the directory
name in TeX.

For those who haven't looked at the TeX code recently, the TeX code
itself creates a shell script to call dvips and ps2image to create
file.png.  The shell script looks roughly like
  dvips ... texfile.dvi > \im...@na...
  ps2image .... \im...@na... htmldirectory\im...@na...g
The TeX command \image@name is given the value imagename from
\begin{image}{imagename}.  So if imagename contains a directory, the
the ps file will be created in that directory relative to ".", but 
the png file will be put in that directory relative to htmldirectory.

One possibility is to add the htmldirectory to the ps file name in
TeX, and then, assuming that "hyperlatex texfile" is run before
"hyperlatex -image texfile", have the necessary directories created by
emacs.

(I'm not sure how clear I'm being....)
