How to correctly embed image in html email

Question

I have some trouble to correctly embed images in html/php email. My .php file just sends out a few text emails. But I want a picture in there. works so far but outlook blocks the image and I have to click download images every time. So I found out that this is the behaviour of linked images. What I need is an embeded image. seems easy but does not work. The image is in the root directory of the index.php but the Mail does not contain the image. Just an error appears: "image cant be displayed". I swear I googled for 2 hours now. How do the companies do that with their signature. I appreciate your help.

I've done the company signature couple days ago and found a lot of problems. For instance, you can set background-image and gmail and most of the email managers will display it, but outlook will not. For images isn't the same. Outlook will display your image, usually when it's https://... In my case I was using firebase hosting to locate the images and 0 problems with that. I use this signature in gmail, and outlook is displaying that tag without any problems, and no need to make any attachment. The data-imagetype is added from outlook when receiving the email and the class x_gmail... too. Hope this will help you, if not I'll try to find a better solution for you.
