mPDF 5.7.1 - image displays as a broken [x]

Question

I have a small issue with mPDF (version 5.7.1).

This code should generate PDF with image file:

 $mpdf = new mPDF();
 $html = \'

        

Answer 1

Ok. After the last comment on question (14:30). Here the exact same code that IS working with mPDF 5.4. And it saves it's output on scripts directory as test.pdf. Firewall issues?

Edited

I have the following directories / files:

• images
  • wallpaper01.jpg
  • wallpaper02.jpg
• index.php (source code)

So these image files are relatively starting from the script directory as it looks like.

require_once __DIR__ . DIRECTORY_SEPARATOR . 'MPDF/mpdf.php';

try {
    $mpdf = new mPDF(); 
    $mpdf->WriteHTML('');
    $mpdf->WriteHTML('');
    $mpdf->Output(__DIR__ . DIRECTORY_SEPARATOR . 'test.pdf', 'F');
} catch(Exception $e) {
    echo $e;
}
