Putting images in a PHP email - php

Question

I have set up a mail form to send emails from my webpage, and I would like to be able to set up images in these emails. This is the code I currently have:
$to = "test#test.com";
$subject = "Emergency details";
$body = "Passport picture: <img src='http://www.test.co.uk/files/passport_uploads/".$passport."'/>";
if (mail($to, $subject, $body)) {
echo("<p>Message successfully sent!</p>");
} else {
echo("<p>Message delivery failed...</p>");
}
When I send this email, the outputs looks like this:
Passport picture: <img src='http://www.test.co.uk/files/passport_uploads/test.jpg"/>
and actually displays the code rather than the picture. Is it possible to make this display the picture instead?
Thanks for any help

Answer 1

That's because you're actually sending a text mail and not an HTML mail. You have to set the proper headers.
Have a look at the mail() function manual : http://php.net/manual/en/function.mail.php
Specifically : Example #4 Sending HTML email
// 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";

Answer 2

you are sending this email as plain text. You should specify that it should be interpreted as an html mail by using mail()'s fourth argument (headers).
Example can be found in the documentation.
The snippet:
// 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";
// Additional headers
$headers .= 'To: Mary <mary#example.com>, Kelly <kelly#example.com>' . "\r\n";
$headers .= 'From: Birthday Reminder <birthday#example.com>' . "\r\n";
$headers .= 'Cc: birthdayarchive#example.com' . "\r\n";
$headers .= 'Bcc: birthdaycheck#example.com' . "\r\n";

Answer 3

You are sending a simple mail and due to this it is interpreted as text only. What you want to do is to send a mail containing html instead of simple text. This require that you include headers to the mail explaining the content of the mail.
Try this:
$headers .= "--$boundary\r\n
Content-Type: text/html; charset=ISO_8859-1\r\n
Content-Transfer_Encoding: 7bit\r\n\r\n";
$to = "test#test.com";
$subject = "Emergency details";
$body = "Passport picture: <img src='http://www.test.co.uk/files/passport_uploads/".$passport."'/>";
if (mail($to, $subject, $body, $headers)) {
echo("<p>Message successfully sent!</p>");
} else {
echo("<p>Message delivery failed...</p>");
}
