embed local image into Mac mail signature

I am trying to create Mac mail signature from HTML.

I do all parts ok, but if I use local images from file, images show when composing the mail, but the receiver will not get them.

<img border=0 width=92
  height=22 src="file:///Users/zadravecm/Library/Mail/V7/MailData/Signatures/image001.png" align=left
  style='margin-top:0px;margin-bottom:15px'>

how to force image to embed into email?

Solution

  • The receiver is not seeing the image because the image src references your computer (in this case the file file:///Users/zadravecm/Library/Mail/V7/MailData/Signatures/image001.png"). For the image to be available on the receiver, you have a few options

    • Upload the image to a online server and use the server url as the img src
    • Embed the image as a base64 String
    • Attach the image to your email and reference it in your html
