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

I have encountered the same problem after migrating the script.

The problem was, that the tmp directory inside the mpdf folder was not writable. I hope it helps someone.
