[SOLVED] Problems with GD

[Renlok]

ive only done a few things before with GD so im pretty noobish with it. But i cant figure out why it just loads the URL but no image

 

<?php
//generates pets image
header ("Content-type: image/jpeg"); 
include('includes/config.php');

$roeid = $_GET['id'];

$query = mysql_query("SELECT t.image, r.wearing FROM roe r LEFT JOIN roetypes t ON ( r.type = t.id ) WHERE r.id = $roeid") or die(mysql_error());
$roeinfo = mysql_fetch_array($query);
$baseimg = $roeinfo['image'];
  //pet image
  $system=explode('.',$baseimg);
if (preg_match('/jpg|jpeg/',$system[1])){
	$background = imagecreatefromjpeg("images/pets/$baseimg"); 
}
if (preg_match('/png/',$system[1])){
	$background = imagecreatefrompng("images/pets/$baseimg"); 
}

//loop though items of clothing
$itemlist = explode(":", $roeinfo['wearing']);
$list = "0";
for($y = 0; $y < count($itemlist); $y++){
	$list .= ",".$itemlist[$y];
}
  //get clothing
  
  $sql = "SELECT image FROM roeclothes
	WHERE id IN ($list)";
  $query = mysql_query($sql) or die(mysql_error());

while($array = mysql_fetch_array($query)){ //create the loop

$clotheimg = $array['image'];
  $insert = imagecreatefromjpeg("images/clothes/clothes/$clotheimg"); 

  imagecolortransparent($insert,imagecolorat($insert,0,0));

  // Get overlay image width and hight for later use

  $insert_x = imagesx($insert); 
  $insert_y = imagesy($insert); 

  imagecopymerge($background,$insert,0,0,0,0,$insert_x,$insert_y,100); //overlay the clothing to the current image
}  //end the loop

  // Output the results as a png image, to be sent to viewer's
  // browser. The results can be displayed within an HTML document
  // as an image tag or background image for the document, tables,
  // or anywhere an image URL may be acceptable.

  imagejpeg($background,NULL,100); 

imagedestroy($background); //clean up the image
?>

start by commenting out the header() call and running the script in your browser. See if there are any errors.

oh yeah im an idiot i never thought of that.

 

also one last question is there a way to save an image generated like this so if you want to pull it up again you dont have to generate it each time.

[Barand]

specify a filename in imagepng() or imagejpeg()

oh, ok thanks thats all i needed.
