[TYPO3] Menu with images

[Xatu Cans]

Hi, I've created a menu with my own pics as menu items. I written this 
TS code and it works fine:

# Main Horizontal dropdown menu
#
lib.mainmenu = HMENU
lib.mainmenu {
   special = directory
   special.value = 61
   1 = TMENU
   1    {
     noBlur = 1
     NO    {
       allWrap = |
       stdWrap.cObject = COA
       stdWrap.cObject    {
         10 = TEXT
         10.wrap = <img src="fileadmin/tv-templates/menu/icon_|.gif" 
border=0 alt="
         10.data = field:subtitle
         20 = TEXT
         20.wrap = |"
         20.data = field:subtitle
         30 = TEXT
         30.wrap = title="|" />
         30.data = field:subtitle
       }
     }
   }
}

but now, I'd like to create an active menu state with new pics and I 
don't know to do it. I've tried with this code, but i dosen't work:

# Main Horizontal dropdown menu
#
lib.mainmenu = HMENU
lib.mainmenu {
   special = directory
   special.value = 61
   1 = TMENU
   1    {
     noBlur = 1
     NO    {
       allWrap = |
       stdWrap.cObject = COA
       stdWrap.cObject    {
         10 = TEXT
         10.wrap = <img src="fileadmin/tv-templates/menu/icon_|.gif" 
border=0 alt="
         10.data = field:subtitle
         20 = TEXT
         20.wrap = |"
         20.data = field:subtitle
         30 = TEXT
         30.wrap = title="|" />
         30.data = field:subtitle
       }
     }
   }


     ACT = 1
     ACT  {
       allWrap = |
       stdWrap.cObject = COA
       stdWrap.cObject    {
         10 = TEXT
         10.wrap = <img src="fileadmin/tv-templates/menu/icon2_|.gif" 
border=0 alt="
         10.data = field:subtitle
         20 = TEXT
         20.wrap = |"
         20.data = field:subtitle
         30 = TEXT
         30.wrap = title="|" />
         30.data = field:subtitle
       }
     }
}

Can anybody help me? thanks
