Are you having problems with images not displaying in DomPDF generated PDFs?
The probable reason is because you’re linking your images in HTML with a path from the script or with an absolute URL like this:
<img src="images/myimage.jpg" />
<img src="http://domain.com/images/myimage.jpg" />
The solution is to change the image SRC to the absolute path on the server, like this:
<img src="/var/www/domain/images/myimage.jpg" />
That will fix the problem!
