Auto Responder HTML Code do not add image properly

I was trying to make some changes in the autoresponder of 3CX in my linux wordpress hosting, before editing i read at the bottom it says: “HTML and the following shortcodes can be used: User’s name: {wplc-user-name} User’s email address: {wplc-email-address}”
So I edited the emial in the cleanest HTML Possible, the email look just fine when i tried to open it as a template in browser, but the same code after saving changes and make the image non working.
I tried almost everything, like different formats of images and different ways to insert email in html, but same problem. Now before anyone say that I should not use image, I want to, since it is the logo of my company and that is the only image i want to use. I want to know how i can, and i am elaborating the problem:

Example of the image i paste in the box right before i save it:

Example of the image after i click “Save Settings”:

Please help me as soon as possible, i want the site up and running.
