How to embed image placed inside the excel into the .htmlbody of vbascript

This is my code of the .htmlbody

    .htmlBody=<html><center><img src='https://website.com/images/logo-small.png'></center></html>"

However, it needs to be downloaded before you can see the logo. So I put the logo inside the excel file, how do I convert it into an shape object and concatenate it inside the .htmlbody
