title: php image type, mozila and IE7
body: <p>i insert image in page and strangely I get a picture of the types.</p>
  
  <p>show type with: $_FILES['img']['type'].</p>
  
  <p>Result:</p>
  
  <pre><code>Firefox: image/jpeg
  IE7: 'image/pjpeg'
  
  Firefox: image/png
  IE7: image/x-png
  </code></pre>
  
  <p>Now i use this filter:</p>
  
  <pre><code>$type_filter = array('image/gif', 'image/jpeg', 'image/png', 'image/jpg', 'image/bmp', 'image/x-png', 'image/pjpeg');
  </code></pre>
  
  <p>It is good, or something else is missing?
  Thanks</p>
