I have a configurable product set up with two simple products associated to it. For demonstration purposes I have used the configurable product "Pet Test" with the two simple products "Test Product Dog" & "Test Product Cat". The url for demonstration is: https://www.design-a-cake.co.uk/pet-test.html

The initial problem I had was I got the error: Invalid method Mage_Catalog_Block_Product_View_Media::isGalleryImageVisible

I added the function as such in Media.php that I found in a template file online (cannot be sure if it is correct)

    public function isGalleryImageVisible($image)
    if (($filterClass = $this->getGalleryFilterHelper()) && ($filterMethod = $this->getGalleryFilterMethod())) {
        return Mage::helper($filterClass)->$filterMethod($this->getProduct(), $image);
    return true;

Now the url loads fine but it does not get the child images when they are selected in the dropdown, it simply shows the parent image but larger? The description changes but is duplicated. If you look at the url you will see quite clearly the issues.

Does anybody have any ideas about this? Thank you.

Its seems js issue your console screenshot is below try these steps to get it fix

-Open dac/js/app.js change image.elevateZoom();


if ($j('.review-product-list').length == 0) { image.elevateZoom(); }

enter image description here

  • Thank you for the reply. I tried that but the problem persists. I can't figure out if it is a javascript issue or php issue that prevents images from being displayed. As mentioned, I added the function myself from another theme file so I cannot be sure if it is used correctly. Commented Nov 1, 2018 at 20:34
