Image is not shown in PDF file using dompdf
use full directory path with .jpg image
It works 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';?>"/>
Don't put full path of URL, just put foldername/filename.jpg
Example:
<img src="uploads/kuruvi.jpg">
