I have created a base64 image to be sent via email to the customer on there mobile device It works in the email app but the gmail app shows a missing image
Is that just google mail blocking data images for security? There's no button to show images either
Code:
$headers = "From: [email protected]\r\n";
$headers .= "Reply-To: [email protected]\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$imagedata = file_get_contents("http://www.barcodesinc.com/generator/image.php? code=12345&style=68&type=C128B&width=180&height=70&xres=1&font=1");
$base64 = base64_encode($imagedata);
$message ="<img src='data:image/png;base64,$base64'>";
mail($to,$subject,$message,$headers);</pre>

Always show images On your Android phone or tablet, open the Gmail app . your account. Under "Data usage," tap Images. Tap Always show.
On your computer, go to Gmail. See all settings. Scroll down to the "Images" section. Click Always display external images.
Gmail on the web: Compose a message, and then drag and drop the picture from your computer to the desired position in the email. Or, position the cursor where you want the image to appear, select Insert Photo > Inline, then choose your photo and select Insert.
Base64 is also widely used for sending e-mail attachments. This is required because SMTP – in its original form – was designed to transport 7-bit ASCII characters only. This encoding causes an overhead of 33–37% (33% by the encoding itself; up to 4% more by the inserted line breaks).
It's google blocking images. Google striped out most inline css and other 'likely' vulnerablilities that cause harm to the end-users' system. Unfortunatly this is the case. However i still think you should never embed your images in e-mail, because you have a lot of mobile users with dataplans. Seems a bit rude.
