Fix Open Graph Image Tag Using Small Image in ISC

Problem

ISC uses the small “standard” image for the Open Graph image tag with filename ending with “_std.jpg” which should use the “zoom” image instead.

Solution

In /public_html/includes/classes/class.product.php

Find

$this->_opengraph_image = $productImage->getResizedUrl(ISC_PRODUCT_IMAGE_SIZE_STANDARD, true);

Replace

$this->_opengraph_image = $productImage->getResizedUrl(ISC_PRODUCT_IMAGE_SIZE_ZOOM, true);

Result

<meta property="og:image" content="https://www.moddiy.com/product_images/f/021/TB2AriHq3MPMeJjy1XbXXcwxVXa_%21%2165511238__07684_zoom.jpg" />
