Replace image field with Product reference type image

I All,

A way to replace image field with another field: product variation image field

Developing a drupal commerce site, I trying to edit the block wishlist.tpl.php.
I would like to replace ( field_single_image ) with ( field_imagine ).
I did the replacement , but no image display.

The field_imagine field is a Product reference type ( widget: Inline entity form )

Here the code I want to edit

<?php foreach($wishlist as $key => $value):
				$single_image = $value->field_single_image['und'][0]['uri'];
				?>
				<div class="clearfix m_bottom_15 relative cw_product">
					<img src="<?php print image_style_url('80x80',$single_image);?>" alt="" class="f_left m_right_15 m_sm_bottom_10 f_sm_none f_xs_left m_xs_bottom_0">
					<a href="<?php print drupal_get_path_alias('node/'.$value->nid);?>" class="color_dark d_block bt_link"><?php print $value->title;?></a>
				</div>
				<hr class="m_bottom_15">
			<?php endforeach;?>

This is the code doesn’t work:

		<?php foreach($wishlist as $key => $value):
				$single_image = $value->field_imagine['und'][0]['uri'];
				?>
				<div class="clearfix m_bottom_15 relative cw_product">
					<img src="<?php print image_style_url('80x80',$single_image);?>" alt="" class="f_left m_right_15 m_sm_bottom_10 f_sm_none f_xs_left m_xs_bottom_0">
					<a href="<?php print drupal_get_path_alias('node/'.$value->nid);?>" class="color_dark d_block bt_link"><?php print $value->title;?></a>
				</div>
				<hr class="m_bottom_15">
			<?php endforeach;?>
