To add a new banner to your MyMarketingWebsite simply go to the Banner Manager and fill in the following three details after clicking "Add New Banner"
In the TITLE section: Put the name of what you want to call banner (for your reference only)
In the URL section: Put the link to which you want people to be directed once they click on your banner
In the Banner Location Section: Put the path to where the banner image file is stored online. (This is probably the trickiest part - you just need to put the full link to where the banner is located online e.g. http://www.mymarketinggolmdine.com/images/banner1.gif or whatever).
