title: Magento How to remove Black image from Image backgrounds
body: <p>I'm new to Magento. I was so confused with the images used in magento. I have changed the default image size 135x135 in product lists to 300X400. But now the problem is, the exact product page image is having black background image &amp; while inspect element it's showing the size as 267x267.</p>
  
  <p>Plz explain me. I want the image size in </p>
  
  <ol>
  <li>product page as 300X400</li>
  <li>Inner exact product image as 300X400</li>
  <li>Also i'm using zoom effect extension. The image should not get pixelate while onhover. So what is the image size should i use while upload product image?</li>
  </ol>
