mPDF not rendering images (mPDF error: IMAGE Error Could not find image file)

Question

I ran across this issue today. My problem was that the domain name I was using didn't resolve back to the server when accessed from the server. I added an entry to the hosts file on the server, and images started showing.

Your equivalent hosts file entry of what fixed my problem would be:

127.0.0.1 www.aibsonline.co.uk

Or otherwise ensure that www.aibsonline.co.uk resolves to your server in the DNS that your server uses.

It appears that mPDF accesses images as a cURL web client, so DNS on the server needs to be configured correctly to refer back to itself.
