Display images according to quantity of chosen combination

[tomikk]

Hi! I wanted to display customers 'images' according to quantity in stock. It was ok until products got combinations. It does not show good image. Below is my code - how can I display image according to combination? Thank you for help.

{if ($product->quantity >= 11) || $allow_oosp || !$product->available_for_order || $PS_CATALOG_MODE}<p id="last_quantities"><img src="#image1"></p>{/if}
{if ($product->quantity >= 3 && $product->quantity <= 10) || $allow_oosp || !$product->available_for_order || $PS_CATALOG_MODE}<p id="last_quantities"><img src="#image2"></p>{/if}
