Magento - How to Get Related Image Options

I am working on my first magento deployment. Got a pretty customized theme created ... by removing some non-standard settings now:

One of my main types of products is the office chair, which I created as a complete product. There are many options for this type of product (about 100 fabric options, arm style, lumbar, headrest, etc.), and I need to be able to display an image for each of them on the catalog / product / view page.

Being a related product (and I will refrain from any discussion about whether this is a suitable type of product - we went in a circle, discussing between custom and related) - each product is assembled from several simple products (as options). These simple products may have images uploaded, and I did it. Now I want to get the urls for those from the media folder ...

After some hunting, these are, apparently, the essential elements:

theme /../ template / catalog / product / view / options.phtml

<?php $_options = Mage::helper('core')->decorateArray($this->getOptions()) ?>
<dl>
    <?php foreach($_options as $_option): ?>
        <?php echo $this->getOptionHtml($_option) ?>
    <?php endforeach; ?>
</dl>

theme /../ template / package / catalog / product / view / type / bundle / options / select.phtml

<?php /* @var $this Mage_Bundle_Block_Catalog_Product_View_Type_Bundle_Option_Select */ ?>
<?php $_option      = $this->getOption(); ?>
<?php $_selections  = $_option->getSelections(); ?>

I finally found found in: getSelections()

class Mage_Bundle_Model_Resource_Price_Index extends Mage_Core_Model_Resource_Db_Abstract
{ ...


    /**
        * Retrieve bundle options with selections and prices by product
       *
        * @param int $productId
        * @return array
        */
       public function getSelections($productId)
       {
           $options = array();
           $read = $this->_getReadAdapter();
           $select = $read->select()
               ->from(
                   array('option_table' => $this->getTable('bundle/option')),
                   array('option_id', 'required', 'type')
               )
               ->join(
                   array('selection_table' => $this->getTable('bundle/selection')),
                   'selection_table.option_id=option_table.option_id',
                   array('selection_id', 'product_id', 'selection_price_type',
                       'selection_price_value', 'selection_qty', 'selection_can_change_qty')
               )
               ->join(
                   array('e' => $this->getTable('catalog/product')),
                   'e.entity_id=selection_table.product_id AND e.required_options=0',
                   array()
               )
               ->where('option_table.parent_id=:product_id');

           $query = $read->query($select, array('product_id' => $productId));
           while ($row = $query->fetch()) {
               if (!isset($options[$row['option_id']])) {
                   $options[$row['option_id']] = array(
                       'option_id'     => $row['option_id'],
                       'required'      => $row['required'],
                       'type'          => $row['type'],
                       'selections'    => array()
                   );
               }
               $options[$row['option_id']]['selections'][$row['selection_id']] = array(
                   'selection_id'      => $row['selection_id'],
                   'product_id'        => $row['product_id'],
                   'price_type'        => $row['selection_price_type'],
                   'price_value'       => $row['selection_price_value'],
                   'qty'               => $row['selection_qty'],
                   'can_change_qty'    => $row['selection_can_change_qty']
               );
           }

           return $options;
       }

so we return an array with selection_id, product_id, price_typeetc .... but nothing does not refer to the URL-address of the image for this selection ...

Given that:

class Mage_Catalog_Helper_Product extends Mage_Core_Helper_Url
{ ...
public function getImageUrl($product)
        {
            $url = false;
            if (!$product->getImage()) {
                $url = Mage::getDesign()->getSkinUrl('images/no_image.jpg');
            }
            elseif ($attribute = $product->getResource()->getAttribute('image')) {
               $url = $attribute->getFrontend()->getUrl($product);
           }
           return $url;
       }
