Imagenes en pdf con dompdf

[andoencombi]

Hola a todos:

Estoy realizando un codigo en el cual genero un pdf con la libreria de dompdf, paso datos y genera bien el pdf, el problema esta en que cuando quiero poner una imagen y redimensionarla solamente me sale el espacio de la imagen pero no la imagen, este es mi codigo para generar el pdf

Código PHP:

  $strHTML="imagen<br>
<img src=\"pruebaimg/imagen2.php?imagen=URL_de_la_imagen\" />
<br>termina imagen";
 
require_once("pdf/dompdf-0.5.1/dompdf_config.inc.php");
 
$dompdf=new DOMPDF();
$dompdf->load_html($strHTML);
$dompdf->render();
$dompdf->stream("FichaPDF.pdf");
exit(0); 
   

el codigo de imagen2.php es este

Código PHP:

  include("resize.php");
    $imagen=$_GET['imagen'];
    $thumb=new thumbnail($imagen);
    $thumb->size_width(180);
    $thumb->show(); 
   

y el codigo de resize.php es este

Código PHP:

  class thumbnail
{
    var $img;
 
    function thumbnail($imgfile)
    {
        //detect image format
//detect image format | deprecated way //$this->img["format"]=ereg_replace(".*\.(.*)$","\\1",$imgfile);
#        $this->img["format"]=end(explode(".",$imgfile));
#        $this->img["format"]=strtoupper($this->img["format"]);
 
        $this->img["format"]=ereg_replace(".*\.(.*)$","\\1",$imgfile);
        $this->img["format"]=strtoupper($this->img["format"]);
        if ($this->img["format"]=="JPG" || $this->img["format"]=="JPEG") {
