Problem:
People who have changed their XMOSAIC (etc) default background
colour to black are unable to see the tables, figures, symbols
since the GIFs are displayed as black-on-black under html.
Solution:
Re-run latex2html, but without running the
giftrans routine (which can be turned off using via the
GIFTRANS environment variable in the latex2html.config file).
This will result in the background colour of all GIFs being set to
white (whilst the foreground colour used for the text/image remains black)
and hence visible.
HOWEVER: remember that black is not the default background colour for
most WWW viewers, and the GIFs with white backgrounds produced
by not running giftrans may annoy users who do have
kept their background colour the default when viewing documents with
many inlined mathematical sysmbols
(see Section 8.3.1).
