Images broken in alerts SharePoint 2013

Hello,

Hoping someone could assist me.

1. I have looked @ the following blog http://blogs.msdn.com/b/sharepointdeveloperdocs/archive/2007/12/14/how-to-customizing-alert-emails-using-ialertnotificationhandler.aspx - Visual Studio beginner
2. If someone has used "Bamboo Workflow Conductor to fix Broken Links and Images in SharePoint Emails - please advise {how I can configure it}

We have several daily list alerts set up - employees receive email alerts when a SharePoint list item is added.  Within the alert, all text items appear ok, but any images included just appear as "broken" links.   This is because the"src" tag has a relative URL to the image (from perspective of the Sharepoint server). 

When the employee is viewing the alert, how can I a make the images appear? I need a way to have the "src" tag on these alerts to have the full sharepoint site address instead of the relative path.  i.e. instead of "img src=/Shared Documents/images/image.jpg", it should instead be "img src=https://intranet.company.com/Shared Documents/images/image.jpg"

Thanks
