title: Thumbnail images not displayed Magento after clearing cache
body: <p>Almost all of my thumbnail images are not displayed after I cleared Magento cache from backend. The problem is only with Thumbnail Images of sets available and similar products and related products images . All category and products pages images seems to be fine.</p>
  
  <p>In order to troubleshoot I did the following:</p>
  
  <ol>
  <li>Made Media Folder globally read write and executable (<code>chmod -R 777 ./media</code>)</li>
  <li>Cleared cache again and then loaded the pages.</li>
  <li>Deleted the cache folder of <code>/var/www/media/catalog/products/cache..</code> Magento recreated cache still no images were displayed </li>
  <li>Increased PHP memory limit to 512MB </li>
  </ol>
  
  <p>Any other guesses, I  need to try to fix this. It's only with small thumbnail images and everything was fine until I deleted cache from backend. </p>
