imagecreate in loop - either creating black image or not resizing

[richrock]

Hi all,

 

Been making myself really wound up with this one.  I need to upload three images, and I've created a loop to do so.  Not a problem so far.  I've opted to use php's built-in functions as they are far superior to another open source one I got referred to...

 

Now my problem is this - I can either create the black jpg in the new filename I need, or copy the image without it resizing.  I've checked all the manuals for the functions on php.net (where I got the source code from) but it's not working - can anyone see if I'm missing a trick?

 

	// Init the image counter
	$img_number = 0;
	//echo "Img Num: ".$img_number."<br />";

	//Process_Image($auct_id, $userid, $tmp_name, $name, $img_number);

	// Upload the images - redeveloped to match the existing auction system
	// Here we upload our images, and then set 
        foreach ($_FILES["pictures"]["error"] as $key => $error) {

		if ($error == UPLOAD_ERR_OK) {

    //Check if GD extension is loaded
    if (!extension_loaded('gd') && !extension_loaded('gd2'))
    {
        trigger_error("GD is not loaded", E_USER_WARNING);
        return false;
    }

                $th_width = '62';

                $lg_width = '892';
                $lg_height = '1338';
                $or_width = '892';
                $or_height = '1338';

			$tmp_name = $_FILES["pictures"]["tmp_name"][$key];
                echo "TMP Name: ".$tmp_name." - ".$img_number."<br />";

                // Content type
                //header('Content-type: image/jpeg'); // if this is on it creates a header error, despite being at the top of the file.
                //copy($path.$newname,$path);
                copy($path.$newname,$orig_path);
                copy($path.$newname,$thumb_path);

as you can see I need to resize the same image to 5 different sizes, due to thumbnails/original images being displayed on various pages with different size constraints.  Any ideas/suggestions welcom.
