[l2h] To choose icon image format

[Shigeharu TAKENO]

I use latex2html-2K.1. We can select the image format, GIF or PNG,
by using option -image_type or setting $IMAGE_TYPE in the initial
file .latex2html-init. 

However, these methods have no effect to icon image files, since
the format for them are defined in the file l2hconf.pm as 
followings: 

 @IMAGE_TYPES = qw(png gif);
 $IMAGE_TYPE  = $IMAGE_TYPES[0];
 ...
 ...
 %icons = ( 
    'cross_ref_visible_mark' , "crossref.$IMAGE_TYPE",
 ...

I think that the user who wants to use GIF image also wants to 
use GIF icons, and one who wants to use PNG image also wants to
use PNG icons. But, under the current version, any user can 
choose just one image formats icons, I think.

Please tell me the simple way to use different icon format 
from the one defined at install instruction, under the multi-user
environments.
