Well, then it might be reasonable to define two separate arrays
%icons_gif and %icons_png in l2hconfig.pm and then, in latex2html after
the "if ($INIT_FILE) {...}" block, assign one of them to %icons based on
the actual $IMAGE_TYPE (possibly set by -image_type or in $INIT_FILE),
provided %icons is still undefined.
