Create custom category navigation wordpress - wordpress

Question

I want to create a custom category navigation 3 level in wordpress.
I don't want to use php wp_nav_menu(), because i need to add cateogry thumbnail inside the navigation.
I found this code :
<?php // Create category navigation with posts for each subcat
$categories = get_categories();
$catID = $cat->cat_ID;
foreach ($categories as $cat) {
if($cat->category_parent == 0){ //If is a top level category
$subcategories = get_categories('child_of='. $cat->cat_ID);
if (count($subcategories)>0){ ?>
<li class="haschild"><a><?php echo $cat->name; ?><span class="image"><img src="<?php echo z_taxonomy_image_url($cat->term_id); ?>" /></span></a>
<?php } /* end if has subcats */
else { // else; does not have childen ?>
<li><?php echo $cat->name; ?><span class="image"><img src="<?php echo z_taxonomy_image_url($cat->term_id); ?>" /></span></li>
<?php } //end else ?>
<?php // Get the subcats !!! THIS RETURNS ALL DECENDING LEVELS.
$subcategories = get_categories('child_of='. $cat->cat_ID);
if (count($subcategories)>0){
echo "<ul class='sub-menu'>";
foreach ($subcategories as $scat) { ?>
<li><?php echo $scat->name; ?><span class="image"><img src="<?php echo z_taxonomy_image_url($scat->term_id); ?>" /></span></li>
<?php
echo "";
}
echo "</ul> </li>"; // Close the Child UL DIV and parent LI
} //endif has subcats ?>
<?php } //end if parent ?>
<?php } //end foreach ?>
But it doesn't work on 3 level, just on 2 level.
you can look the menu directly on my website : http://www.designsd.fr/ap/
Do you have an idea to change it ?

Here is the updated code with a new loop level:
<?php // Create category navigation with posts for each subcat
$categories = get_categories();
$catID = $cat->cat_ID;
foreach ($categories as $cat) {
if($cat->category_parent == 0){ //If is a top level category
$subcategories = get_categories('child_of='. $cat->cat_ID);
if (count($subcategories)>0){ ?>
<li class="haschild"><a><?php echo $cat->name; ?><span class="image"><img src="<?php echo z_taxonomy_image_url($cat->term_id); ?>" /></a></span>
<?php } /* end if has subcats */
else { // else; does not have childen ?>
<li><?php echo $cat->name; ?><span class="image"><img src="<?php echo z_taxonomy_image_url($cat->term_id); ?>" /></span></li>
<?php } //end else ?>
<?php // Get the subcats !!! THIS RETURNS ALL DECENDING LEVELS.
$subcategories = get_categories('child_of='. $cat->cat_ID);
if (count($subcategories)>0){
echo "<ul class='sub-menu'>";
foreach ($subcategories as $scat) {
$child_subcategories = get_categories('child_of='. $scat->cat_ID);
if (count($child_subcategories)>0){ ?>
<li class="test"><a><?php echo $scat->name; ?><span class="image"><img src="<?php echo z_taxonomy_image_url($scat->term_id); ?>" /></span></a>
<?php } else { ?>
<li><?php echo $scat->name; ?><span class="image"><img src="<?php echo z_taxonomy_image_url($scat->term_id); ?>" /></span>
<?php }
if (count($child_subcategories)>0){
echo "<ul class='sub-menu'>";
foreach ($child_subcategories as $sscat) { ?>
<li><?php echo $sscat->name; ?><span class="image"><img src="<?php echo z_taxonomy_image_url($sscat->term_id); ?>" /></span></li>
<?php }
echo '</ul>';
}
?>
</li>
<?php;
}
echo "</ul> </li>"; // Close the Child UL DIV and parent LI
} //endif has subcats ?>
<?php } //end if parent ?>
<?php } //end foreach ?>
