title: Unable to include image in pdf using cfdocument/cfcontent
body: <p>I'm streaming images from outside the web root, using cfcontent. While the images are displayed correctly when the various pages are called directly in the browser, the images show a red X inside the generated pdf. On the export page:</p>
  
  <pre><code>&lt;cfsavecontent variable = "gridCode"&gt;
      &lt;cfinclude template="pathToGeneratedPage.cfm" &gt;     
  &lt;/cfsavecontent&gt;
  &lt;cfdocument format="pdf" filename="#filename#" overwrite="yes" localUrl="yes"&gt;
      &lt;cfdocumentsection &gt;
          &lt;cfoutput&gt;#gridCode#&lt;/cfoutput&gt;     
      &lt;/cfdocumentsection&gt;
  &lt;/cfdocument&gt;
  </code></pre>
  
  <p>On the page with the content to be generated:</p>
  
  <pre><code>&lt;img src="pathToDisplayPhoto.cfm?image=#someImage#" /&gt;
  </code></pre>
  
  <p>On the displayPhoto.cfm page:</p>
  
  <pre><code>&lt;cfcontent type="image/*" file="#pathToUploadFolderOutsideWebRoot##url.image#" deleteFile = "No"&gt;
  </code></pre>
  
  <p>I included the cfdocument attribute localUrl="yes" because the default (no) was not working. Setting explicitly to "no" doesn't work either.</p>
  
  <p>Any suggestions?</p>
