Add is gone so do not know who you are referring to. If you could archive the ad that would be great.
1) Archive the page - goto archive.is and paste the page URL and click on the "save page" button (or use the bookmark applet as described above once you have that set up)
2) From the archived page - click on the "share" link near the top of the page
3) Copy the code from the "HTML Code" box and paste it into your PERB post
