How can I embed a linked local image in an Apple Mail signature?

Solution 1:

Here is my solution:

  1. Open the picture in Preview (or open the html in a browser)
  2. Cmd-A to select all, Cmd-C to copy
  3. Create a new signature and paste in the contents

I have verified that this solution works for local pictures and simple html snippets.

Solution 2:

I have found that Mac Mail does not allow for embedded images in their signatures. If you are designing an HTML signature, I would use the img src tag to load a remote image. Try using googleplus or googledocs to save the image you want to include. You can then control it using HTML and CSS styles.
