Dompdf remote image is not displaying in pdf

 Step 1

Step 2

I found its solution, you just need to double check the image path,

Considering your live server image path

<img src="http://www.example.com/public/images/thumb.png">

You just need to change it to,

<img src="public/images/thumb.png">

Note: Make sure that, all settings are same as you have already made.

I hope this will help you.
