title: Including every possible entry in replacement
body: <p>I made this piece of code to automatically add an alt-text (using the title) to all the images in the description of my page. By replacing alt="" with alt="TITLE". </p>
  
  <p>The code :</p>
  
  <pre><code>$this-&gt;data['description'] = str_replace('alt=""', 'alt="' . $product_info['name'] . '"', html_entity_decode($product_info['description'], ENT_QUOTES, 'UTF-8'));
  </code></pre>
  
  <p>It works perfectly but the problem is that all the images in the description already have an alt-text (always different), thus they don't get replaced. </p>
  
  <p>Instead of replacing alt="" it should replace alt="EVERYPOSSIBILITY" with the title.</p>
  
  <p>Hope you can help me out with this problem.</p>
