Using Absolute References (supported)

An Absolute Reference provides the complete http address, the directory path, and the file name. For instance, if you had a file named "logo.gif" in a directory called "images" under the URL "https://www.emailonacid.com" you would link to it as follows:

<img align="bottom" src="https://media.emailonacid.com/wp-content/uploads/2018/07/Sposta-logo.gif">

In html context, this might appear as:
<img align="bottom" src="/images/logo.gif">
