createthumb()... gd prob?

[MikeDXUNL]

I am in ... mysite.com/sub/adm/

 

and uploading to mysite.com/sub/wallpapers/

-----

 

well my GD is all a-go. but... for some reason, the function is not working properly.

 

In a form, I choose a category.. lets say 'pets' and then browse for the wall...

 

so then it checks the image variants and if everything is cool.. it uploads it and moves it

 

 

uploadwall.php:

<?php
//Define Variables
####################################
$maxfilesize = 2000000;
####################################


// Check if file was uploaded
if (!is_uploaded_file($_FILES['wallpaper']['tmp_name'])) {
    $error = "you didn't select a file to upload.<br />";
// Check if file is < size range
} else {
    if ($_FILES['wallpaper']['size'] > $maxfilesize) {
        $error = "your image file was too large.<br />";
        unlink($_FILES['wallpaper']['tmp_name']);
    } else {
// Check if acceptable file extension
        $ext = strrchr($_FILES['wallpaper']['name'], ".");
        if ($ext != ".gif" AND $ext != ".jpg" AND $ext != ".jpeg" AND $ext != ".bmp" AND $ext != ".GIF" AND $ext != ".JPG" AND $ext != ".JPEG" AND $ext != ".BMP") {
            $error = "your file was an unacceptable type.<br />";
            unlink($_FILES['wallpaper']['tmp_name']);
// Upload and Replace photo
        } else {

$var_x = randomkeys(1);

            $newname =  $var_x."_".$up_catname."_".$_FILES['wallpaper']['size'].$ext;
            
            
            $newname_th1 = $var_x."_".$up_catname."_".$_FILES['wallpaper']['size']."_th1".$ext;
            
          
            $newname_th2 = $var_x."_".$up_catname."_".$_FILES['wallpaper']['size']."_th2".$ext;
            
            
            move_uploaded_file($_FILES['wallpaper']['tmp_name'],"../wallpapers/".$up_catname."/".$newname);
            mysql_query("INSERT INTO wallpaper (wallname, walldesc, catname, author, date, total_votes, total_value) VALUES ('$up_wallname', '$up_walldesc', '$up_catname', '$username', '$date', '0', '0')") or die (mysql_error());
            
               createthumb('../wallpapers/'.$up_catname.'/'.$newname.'', '../wallpapers/'.$up_catname.'/thumb1/'.$newname_th1.'', 160, 120);
               
                            createthumb('../wallpapers/'.$up_catname.'/'.$newname.'', '../wallpapers/'.$up_catname.'/thumb2/'.$newname_th2.'', 320, 240);
      	    }
    	}
}
?>

 

 

--- $up_catname would be equal to 'pets' and size to whatever the image size is...

 

here is

 

createthumb()

<?php
function createthumb($name,$filename,$new_w,$new_h)
{
$system = explode(".",$name);
if (preg_match("/jpg|jpeg/",$system[1])){$src_img = imagecreatefromjpeg($name);}
if (preg_match("/png/",$system[1])){$src_img = imagecreatefrompng($name);}
$old_x = imageSX($src_img);
$old_y = imageSY($src_img);

	$thumb_w = $new_w;
	$thumb_h = $new_h;

$dst_img = ImageCreateTrueColor($thumb_w,$thumb_h);
imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y);

if (preg_match("/png/",$system[1]))
{
	imagepng($dst_img,$filename); 
} else {
	imagejpeg($dst_img,$filename); 
}

imagedestroy($dst_img); 
imagedestroy($src_img); 
}
?>

 

 

the error i am getting is:
