How to Embed Images in HTML Emails Using PHPMailer or Alternative Approaches?

Embedding Images in HTML Emails

Sending HTML emails with embedded images can enhance email aesthetics and convey information effectively. While using inline images from a server is a straightforward approach, it presents a few challenges.

Using an Email Library

One recommended solution is to utilize a library such as PHPMailer. This library simplifies the process and proactively handles common issues.

Inline Image Attachments

To embed images in an HTML email using PHPMailer, you need to create an "inline attachment." This involves associating an image with a specific Content Identifier (CID), which is then referenced within the HTML document.

For example, if you want to embed an image named "my-photo.jpg" with the CID "my-photo," you would use the following code:

<code class="php">$mail->AddEmbeddedImage('my-photo.jpg', 'my-photo', 'my-photo.jpg');</code>

Building the HTML Email

The HTML code of your email should include a reference to the embedded image using the CID:

<code class="html"><img src="cid:my-photo" alt="my-photo" /></code>

Sending the Email

To send the HTML email with embedded image, you can use PHPMailer's Send() method:

<code class="php">$mail->Send();</code>

Alternative Approach

If you prefer not to use PHPMailer's preferred method (e.g., SMTP), you can still leverage the library for constructing the email and send it manually:

<code class="php">$mime_message = $mail->CreateBody(); // Retrieve message content
// Send the message using your preferred method</code>

By embracing the techniques described above, you can effortlessly embed images into HTML emails, unlocking the power of visual communication within email marketing campaigns.
