adding custom background

[sphinx]

Hello,

 

I'm using this PHP code to generate a random number and display into  PHP number, How could I add my own custom background for it with custom size:

 

<?php
// Set the content-type
header('Content-Type: image/png');
srand ((double) microtime( )*1000000);
$random_number = rand(0,1000000);
// Create the image
$im = imagecreatetruecolor(90, 30);

// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
$red = imagecolorallocate($im, 255, 0, 0);
$blue = imagecolorallocate($im, 255, 0, 0);
imagefilledrectangle($im, 0, 0, 399, 29, $white);

// The text to draw
$text = $random_number;
// Replace path by your own font path
$font = 'arial.ttf';

// Add some shadow to the text


// Add the text
imagettftext($im, 20, 0, 10, 20, $blue, $font, $text);

// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>

 

Would something like:

 

$im = imagecreatefromgif ( "bg.gif" ); 

 

Work, I've tried that, nothing displays.

 

Many thanks.
