Laravel 5 background-images doesn't show up on DOMPDF?

Here is my css code :

#header {
    background-image: url(../assets_frontend/images/pinpdfheader.jpg);
    width: 100%;
    background-repeat: no-repeat;
    background-size:contain;
    height:150px;
}

I am try to convert my html file into DOMPDF but somehow my background-images didn't show up, How to use background-images url on DOMPDF?
