Hello,
Thnaks for your element, we have found a solution for your specific need.
You have already an override of your view product/cart.
You can force your image parameters directly in your override view around line 484 - 485
You have this :
$width = (int)$this->config->get('cart_thumbnail_x', 50);
$height = (int)$this->config->get('cart_thumbnail_y', 50);
Change your
2 parameters "
50" for "
100" (or "200" if required), to get this :
$width = (int)$this->config->get('cart_thumbnail_x', 100);
$height = (int)$this->config->get('cart_thumbnail_y', 100);
Then you can adjust via a custom css your image width.
Regards
