title: SSRS report external image
body: <p>This is SSRS 2012 SQL Server 11.00.2218</p>
  
  <p>When I have external image in report using <code>http://i.imgur.com/g3D5jNz.jpg</code> it works. </p>
  
  <p>but when I use <code>file:///\\ImageServer\April.jpg</code> 
  I got this error on the html </p>
  
  <pre><code>&lt;IMG onerror=this.errored=true; src="" errored="true"&gt;
  </code></pre>
  
  <p>I have had this working for about 1 year. Then suddenly stop working. 
  Steps I have done to troubleshoot and still not fixing the issue: </p>
  
  <ol>
  <li>Check execution account has access to \ImageServer\April.jpg confirmed execution account has access to the imageServer and the file - DONE</li>
  <li>Unload antivirus on the report server then test - DONE</li>
  <li>Reboot report server - DONE but I will try this again </li>
  <li>I looked in C:\Program Files\Microsoft SQL Server\MSRS11.MSSQLSERVER\Reporting Services\LogFiles, and found no error for image related or any error related to the specific report I run</li>
  </ol>
  
  <p>Clues I notice that I don't know how to troubleshoot</p>
  
  <ol>
  <li>when using imgur jpg, the html img src is using some web service AXD file ReportViewerWebControl.axd. I am guessing it uses this to resize or convert the image some how. is it possible that an error happen during conversion/resize?</li>
  </ol>
  
  <p>Could you please suggest how to troubleshoot this further?</p>
