Adding a special image to special group prices

Question

In my store i have a group called "loyal customers" This group of customers gets a special price which i can set in the backend under product-> prices-> group prices. Is there a way of the products with these special group prices to display a lil image in the corner of the product image (like some sites do with products on sale) but the image should of display if the customer is logged in and is within the "loyal customer" group??

Thank you for your help if you can.

<?php
$_helper = $this->helper('catalog/output');
$_product = $this->getProduct();
$enable_upsell =  Mage::getStoreConfig('midmedssettings/labels/enable_upsell');
$replace_upsell =  Mage::getStoreConfig('midmedssettings/labels/replace_upsell');

$helper = $this->helper('midmedssettings/image');
list($defaultImgX, $defaultImgY) = $helper->getDefaultSize();
list($imgX, $imgY) = $helper->getMainSize();
if ( $imgX > 800 ) {
    $imgX = 800;
    $imgY = $helper->calculateHeight($imgX);
}

$product_img_box_width = $defaultImgX;
if ( $defaultImgX != $imgX ) {
    $product_img_box_width = $imgX;
}
//add image border
$product_img_box_width += 18;
