PHPjasperxml не показывает изображения в отчете в формате PDF

Недавно я сделал отчеты в формате PDF с помощью phpjasperxml в веб-приложении с php 5.5.9 и laravel 5.2.0. Я сделал отчет в ireport 5.6.0, и он отлично работает. но когда я пытаюсь показать отчет в формате PDF из веб-приложения, он не показывает мне изображения, которые я помещаю в отчет.
