It did here, so \text{} should be avoided.

OK, the png file *is* transparent here all right (see attachment), so it may come from your library version.
 Sun/Solaris 5.8
 perl 5.6.1
 LaTeX2HTML Version 2002-1 (1.68)
 libpng 1.2.3

Works fine here with this simple .latex2html-init file:
$TRANSPARENT_FIGURES = 0;

1

In fact this is a Perl message, not a l2h one: your .latex2html-init file 
should end with a 1 on a single line to return true

I guess the libraries are missing... maybe due to licensing issues.
There is presently no reason to use gif instesd of png.
Maybe you could browse the latex2html docs and check that libraries needed to
manage graphics are here and up to date. AFAIR, the links are referenced there.
You may check netpbm as well.
