problema ImageJPEG

[mariox]

Su che server hai il dominio?
Windows o Linux?

io ti consiglio di vedere quest'esempio:

   $dest_hires = "../images/artistsphotos/".$imageName."h.jpg";
        $dest_lowres = "../images/artistsphotos/".$imageName."l.jpg";
        $dest_thumbnail = "../images/artistsphotos/".$imageName."i.jpg";

        /*upload full size image to site - if it is hi res we do not want to manipulate it
        want to leave all qualit in tact.*/
        move_uploaded_file($_FILES["fileartimg"]["tmp_name"],"$dest_hires");

        $ims = getimagesize($dest_hires); //now we have dimensions of original image...
   
        /******creating lower res image******/
        $newwidth=ceil($ims[0]/2);//half the width of original file - use ceil() to avoid decimals.
        $newheight=ceil($ims[1]/2);//half the height
   
        $img = imagecreatetruecolor($newwidth,$newheight); //low res img - always use truecolor to prevent any 'wierd' colour effects.
        $org_img = imagecreatefromjpeg($dest_hires); //load in hi res
   
        imagecopyresized($img, $org_img, 0, 0, 0, 0, $newwidth, $newheight, $ims[0], $ims[1]);
        imagejpeg($img,$dest_lowres,80);//save to file low res img.
        imagedestroy($img);
