Is it recommended to store images for newsletters on a web server and reference them in the HTML code, or is there a better approach for handling image attachments in emails sent via PHP?
It is recommended to store images for newsletters on a web server and reference them in the HTML code when sending emails via PHP. This approach ensures that the images are displayed correctly in the email and reduces the size of the email attachments. By linking to the images hosted on a web server, you can also track the number of times the images are viewed.
// Example PHP code to send an email with images linked from a web server
$to = "recipient@example.com";
$subject = "Newsletter with Images";
// HTML content of the email with image links
$message = "
<html>
<body>
<h1>Welcome to our Newsletter!</h1>
<p>Check out our latest products:</p>
<img src='https://example.com/images/product1.jpg' alt='Product 1'>
<img src='https://example.com/images/product2.jpg' alt='Product 2'>
</body>
</html>
";
// Headers to set content type and additional email settings
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
// Send the email
mail($to, $subject, $message, $headers);
