Graphic needed for Privchat 5 and 6
each Privchat sessions has an image, except the last 2.
The last Privchat maybe just stays on the main section of the page at https://www.torproject.org/privchat/ and it may not need one image.
The 5th, tho, had a failing image link that I have commented out on the page.
It would be nice to have some images for those.
