I'm using wp_mail() to send e-mail from our website. However, we would like to include a .gif file on the body of our message. Here's my code, but it's not working.

$to = $contact['Email'];
$from = '[email protected]';

// To send HTML mail, the Content-type header must be set
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
// Create email headers
$headers .= 'From: Testing Mail <'.$from .'>'. "\r\n";

$subject = "Subject Text";
$customer_name = $contact['FirstName'];

$message = '<html><body>';
$message .="<p>message!</p>";
$message .= "<p>message </p>";
$message .= "<img src='img/signature.gif'>";

$message .= '</body></html>';
wp_mail($to, $subject, $message, $headers);

You have to provide the absolute path for your included image, as the receiver of the email does not have a file "signature.gif" in a folder "img" (that's where the client is going to search it)


$message .= "<img src='img/signature.gif'>";


$message .= "<img src='http://yourwebsite.com/PATH/TO/img/signature.gif'>";

Where yourwebsite.com is your website's domain followed by the complete path.

Depending on where you added your code, you can access a WordPress function, to add the domain dynamically. This is useful if you have to move your website to another domain (for a staging/developing enviroment for example). Have a look at get_site_url().

You could use it like this:

$message .= "<img src='" . get_site_url() . "/PATH/TO/img/signature.gif'>";
