not working

You can use Image function:

$this->Image($imagePath,$x,$y,$imageWidth,$imageHeight,$type,$url);

See http://fpdf.org/en/doc/image.htm

// Insert a logo in the top-left corner at 300 dpi
$pdf->Image('logo.png',10,10,-300);

gave error

FPDF error: Some data has already been output, can't send PDF file

$this->Image("logo.png",50,50,200,100,"png","http://www.synthetron.com");

php.net/manual/en/function.set-magi ...

when you disable those 2 lines it show logo

but with wrong dimensions not following the parameters

$this->Image('logo.png',20,20,300,100,'PNG','http://www.synthetron.com');

dimensions are not pixels but milimeters

you can use this function:

function put_img($x,$y,$imageWith,$imagePath,$dpi='72',$url='') {

$imgSize = getimagesize($imagePath);
$imgRatio = $imgSize[0] / $imageWith;

$outWidth = ($imgSize[0]/($imgRatio));
$outHeight = ($imgSize[1]/($imgRatio));

$this->Image($imagePath,$x,$y,$outWidth,$outHeight,'',$url);

}

$this->put_img(50,50,200,"logo.png",300,"http://www.synthetron.com");

that does not fix

set_magic_quotes_runtime() error

pity you cant attach files here
