Icon before each subcategory - how to?

[Gwydion]

I have tried to find a better looking way to group subcategories but am back to the default where they are listed in one line and the width is determined by the td width.
However it might look better if a small icon (circle, dot, whatever) is placed in front of each subcategory.
I assume this must be done in functions.php but I don't know what the correct code would be.
Can somebody pls. help? I do not want images (random or not) from the database, just a small static icon e.g.
o sub 1  o sub 2  o sub 3
o subwithverylongname 4  o sub 5

in includes/functions.php find

Code: [Select]

      $sub_cat_list .= "<a href=\"".$sub_url."\" class=\"subcat\">".$cat_cache[$subcat_id]['cat_name']."</a>";
replace with

Code: [Select]

      $sub_cat_list .= "<a href=\"".$sub_url."\" class=\"subcat\"><img src=\"".get_gallery_image("subcaticon.gif")."\" border=\"0\">".$cat_cache[$subcat_id]['cat_name']."</a>";

upload subcaticon.gif into templates/<your template>/images/ directory
