Hello
One question to clarify are we talking installation by you or installation service performed by us?
Our installation service would install the software on your server integrate it into your vbulletin user login and overall style and place the featured photo block on your vbulletin as such this example.

You may install the software should you be comfortable performing the needed tasks on our installation doc below.
