Images not displaying in email

Question

I have HTML code that displays images correctly when I view the HTML file on my desktop or from our webserver, but not when I send a Campaign.  Why?

Answer

The issue may be that the Template is using "relative paths" to the images instead of "absolute paths".  Relative paths are fine on a webpage because the system knows it can looking in a particular folder on that website to find the image.  However, an image in email has no relationship to a website and the URL must be "fully qualified" in order to display the image.

• A relative image path appears something this:
  <img src="/images/logo.gif">

• An absolute path includes the fully qualified URL, such as:
  <img src=""http://www.mydomain.com/content/themes/images/logo.gif"">
