Base64 email image not showing in Google Mail

Question

I created a base64 image to send an email to a client, there is a mobile device. It works in an email application, but the gmail application shows a missing image

Is this just Google mail for blocking data images for security? There is no button to display images either

The code:

     $ headers = "From: [e-mail] \ r \ n";  $ headers. = "Reply-To: [e-mail] \ 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> 

Answer 1

This Google blocks images. Google shared most of the built-in css and other "probable" vulnerabilities that damaged the end-user system. Unfortunately, this is so. However, I still believe that you should never embed your images in email, because you have many mobile users with dataplans. Seems a little rude.

Google blocks images. Link: 2013 test from the monitor of the campaign for supporting embedded images in HTML email .
