[l2h] Images quolity

[Vladimit]

Hello All !
I'm using latex2html with the following settings:
$ANTI_ALIAS = 1;
$ANTI_ALIAS_TEXT = 1;
$WHITE_BACKGROUND = 1;
$TRANSPARENT_FIGURES = 1;
$TRANSPARENT_IMAGES = 1;

But images are in very poor quolity. Moreover, some of them are on gray 
background.
Analising latex2html output I've found this:

Generating postscript images using dvips ...

/usr/bin/dvips: Font dsrom10 at 8000 not found; scaling 600 instead.
/usr/bin/dvips: Such scaling will generate extremely poor output.

What could I do to fix this trouble ? Could you give me any tips ?
