Remove template image from PHP?

Can someone show please show me how to edit this code so that the image is called from tmpl_xxx and not from the php code?

//--- Get breadcrumb path(left side) ---//
$sDivider = '<img class="bc_divider" src="' . getTemplateImage('bc_divider.png') . '" />';
$aPathLinks = array();
foreach($aPath as $sLink)
$aPathLinks[] = '<div class="bc_unit">' . $sLink . '</div>';
$sPathLinks = implode($sDivider, $aPathLinks);

Hello this function try to find image into your current template dir and if will not find use it from base. Just add all you needed images into your current template dir

I did but it's not working. It keeps calling the image from the base template. This is my CSS code in tmpl_xxx/css/top_menu.css

.breadcrumb img.bc_divider {
background-image:url(../images/images/bc_divider.png);
width: 15px;
height: 30px;
margin: 0px 10px 0px 0px;

Thanks Saha I got it.
