In a dashboard's HTML code, how do I dynamically append a date to an image filename?

Hi,

<row>
    <panel>
      <html>
        <img src="/static/app/search/image.PNG"/> 
   </html>
   </panel>
  </row>

Currently am using above patch of code in my Splunk dashboard to show the picture which is working fine.
But, as per the requirement, the file will change everyday and the filename will change to image_28102016 which includes today's date. So how to add this date field parameter to the filename so that it will pick up the latest file always?

Add this to the top of your dashboard.

    <search><query>| makeresults | eval dt=strftime(_time, "%d%m%Y")</query>
      <done>
        <set token="filename">image_.$result.dt$.jpg</set>
      </done>    
    </search>

And change your IMG tag to this

<img src="/static/app/search/$filename$" />

Hi Sundareshr,

I used this patch of code but still the image is not coming up. Is there any other way to troubleshoot it through any log file where I can see what exact file name its taking.
