DomPDF: Image not readable or empty

Question

Following helped me like charm, at least localy, and even with

def("DOMPDF_ENABLE_REMOTE", false);

The solution is to change the image SRC to the absolute path on the server, like this:

<img src="/var/www/domain/images/myimage.jpg" />

All of the following worked for me:

<img src="<?php echo $_SERVER["DOCUMENT_ROOT"].'/placeholder.jpg';?>"/>
<img src="<?php echo $_SERVER["DOCUMENT_ROOT"].'\placeholder.jpg';?>"/>
<img src="<?php echo $_SERVER["DOCUMENT_ROOT"].'./placeholder.jpg';?>"/>

$_SERVER["DOCUMENT_ROOT"] is C:/wamp/www/ZendSkeletonApplication/public

Thanks to this: lost in code

As there was another answer that suggests enabling the remote option in module.config.php and I can't yet add comments, I thought it would be best to answer that this file does not exist in newer versions of DomPDF.

If you need to include remotely stored images in a newer version you have to pass it as an option to the constructor:

$dompdf = new Dompdf(array('enable_remote' => true));

This fixed the issue I had.

Ok I had the same problem with image using :

<img id="logo" src="/images/flags/fr.png" width="50" alt="Logo">

But if I add a . before /images, without changing anything in dompdf_config.custom.inc, it works

<img id="logo" src="./images/flags/fr.png" width="50" alt="Logo">

Hope it helps

Now (May 2018) the correct way is :

$options = new Options();
$options->set('isRemoteEnabled',true);      
$dompdf = new Dompdf( $options );

You can use base64 encoded image

<img src="{{'data:image/png;base64,' . base64_encode(file_get_contents(@$image))}}" alt="image" >

I solve this problem by using external CSS's full path. This one worked on my linux ubuntu server :

<link href="{{ public_path('css/style.css') }}" />

<img src="{{ public_path('images/image.jpg') }}" />

and work on image.
