What is an absolute image reference?

An absolute reference provides the complete domain address, directory, and filename of a resource, such as an image. For instance, if you had a file named “logo.gif” in a directory called “images” under the domain “https://www.emailonacid.com” you would link to it as follows:


In html context, this might appear as:

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

Most ESPs require absolute references in your HTML email code.
