UE Embedded image data not sending correctly

I'm having problems with embedded images in Universal Email. We embed our company logo at the top of our notification emails, shortened example:

<img src='data:image/png;base64,iVBORw0KGgoAAAANSUhEUg.......... ..........HWR9aRDQEf1/8y8gmUW6JKKK6QAAAABJRU5ErkJggg=='/>

For years its worked fine when using mail_php.php and mailformatting.php. Now we've switched to WA_Email.php its not working correctly, the embedded data gets a url prepended to it:

<img src=3D'https://domain.tld/webassist/email/templates/data:image/=png;base64,iVBORw0KGgoAAAANSUhEUg.......... ..........HWR9aRDQEf1/8y8gmUW6JKKK6QAAAABJRU5ErkJggg=3D=3D='/>

I read a post that said I need to embed the image in the email construction by using:

$Email->AddEmbeddedImage('plugins/images/foxy.png', 'foxy', 'foxy.png', 'base64', 'image/png');

and then call the image in the email template with

<img src=3D\"cid:foxy\">

but this didnt work. I tried with the image in several locations including the same directory as WA_Email.php, and PHPMailer.php, and also describing it from various viewpoints including D:/websites/.... but still nothing. Do you have any suggestions?

The example img data does not really have the 'plugins/' bit in it. Not sure where that's coming from.

This looks like an issue with the file:

webassist/framework/framework.php

Find this line:

$ignore = '/^(https?%3A%2F%2F|https?:\/\/|mailto:|javascript:|callto:|wtai:|sms:|market:|geopoint:|ymsgr:|msnim:|gtalk:|skype:|sip:|whatsapp:|geo:|tel:|#|\/)/i';

and update it to:

$ignore = '/^(https?%3A%2F%2F|https?:\/\/|mailto:|javascript:|callto:|wtai:|sms:|market:|geopoint:|ymsgr:|msnim:|gtalk:|skype:|sip:|whatsapp:|geo:|data:|tel:|#|\/)/i';

That should prevent it from updating the path and causing this issue.

Hi Ray,

Thanks for that. Slight technical hitch... I don't have a framework directory or framework.php.
I have just deleted the email from the page and recreated it, just in case something omitted first time, but still nothing.

My page just requires 'WA_Email.php', and WA_Email.php has no mention of requiring framework.php

I cant find anything in the entire site that references framework.php .

Do I need to put in a "require_once" somewhere?

There is a similar line in the webassist/email/WA_Email.php file.

Try updating line 619 from:

$ignore = '/^(https?%3A%2F%2F|https?:\/\/|mailto:|javascript:|#|\/)/i';

to:

$ignore = '/^(https?%3A%2F%2F|https?:\/\/|mailto:|data:|javascript:|#|\/)/i';

Bingo! That did it.

And in a most unexpected way. Its replaced the embedded

"img src='plugins/data:image/png;base64,iVBORw0KGg....."

with a much shorter

"img src="cid:b709cbe248c945bc6b1....."

The full image data has been added to the end of the file in a nice neat chunk. Its really rather pleasing in an ocd kind of way.
