Images in email signatures – linked or embedded?
The HTML format makes it possible to add images to emails and email signatures. Graphics can be included as:
- linked (hosted) images - online graphical resources are referenced in the email's HTML source by using a URL: <IMG src="https://www.codetwo.com/images/image.jpg">
- embedded images - local graphics are added to emails as hidden attachments (referenced in the email's source via a Content-ID: <IMG src="cid:unique-content-id">).
In the table below you can learn about the advantages and disadvantages of each method.
