I solved this problem by overriding the module's View/Product/Details/Brand.php file's getLogoWidth() and getLogoHeight() methods.
This is the file I created at classes/XLite/Module/<dev_id>/<module_id>/Module/QSL/ShopByBrand/View/Product/Details/Brand.php:
PHP Code:
<?php
// vim: set ts=4 sw=4 sts=4 et:
namespace XLite\Module\<dev_id>\<module_id>\Module\QSL\ShopByBrand\View\Product\Details;
class Brand extends XLite\Module\QSL\ShopByBrand\View\Product\Details\Brand implements \XLite\Base\IDecorator
{
/**
* Get the width of the product's brand logo.
*
* @return integer
*/
public function getLogoWidth()
{
return 200;
}
/**
* Get the width of the product's brand logo.
*
* @return integer
*/
public function getLogoHeight()
{
return 150;
}
}
I then redeployed the store, and the brand images were now bigger on individual product pages.
