Well, we are getting closer. First of all I can confirm that all works
(mostly) fine if the -ldump option is NOT used. So, that should
eliminate the guessing about directory permissions, etc. The images are
created and placed in the correct places. However, when I use -ldump I
get the following printed to the screen:

Also, there is no file "images.fmt" created.

Here is the actual command line extracted from the Makefile:

latex2html -split +1  -dir html -no_math -no_footnode  -local_icons \
                 -ldump -up_url ../mma.html -up_title "Main MMA
Reference" \
                  $(TARG).tex

Under the previous system the .fmt file was created in the html
directory. The permissions for that dir are:

	drwxrwxr-x  2 bob bob  8192 Apr 24 16:12 html/

So, that should be okay.

Maybe some tex-pert can figure out the "I'm stymied" message above :)

Yes, this is an existing document. But, I have cleaned out all the
existing log files, etc. No differences.

I just checked the texmf stuff and the various html files show in the
ls-R file in my main texmf tree. So, that seems to be fine.


Now, a second problem. Which may be related ... so I'm not starting a
new thread. No matter what I do, none of my images are created as
transparent. These are all images created from postscript files. They
are black and white music notation snippets. The conversions insist on
created a grey background with black notes/lines.

I've looked at the docs, etc. but don't see anything to control that. It
should just happen, shouldn't it?
