Image cropping

[SpecialFX]

I have all the cropping done except, i get this error when trying to resample the image:

Warning: imagecopyresampled(): supplied argument is not a valid Image resource in /var/www/vhosts/site.com/httpdocs/staging/cms/modules/crop_image.php on line 29

This is a piece of the code, including line 29 where the error is.

$location = '../'.$uploads.$imageFileName;
$src        = imagecreatefromjpeg($location);
$dst        = imagecreatetruecolor($cropWidth, $cropHeight); 
imagecopyresampled($location, $location, 0, 0, $cropX, $cropY, $cropWidth, $cropHeight, $imageWidth, $imageHeight);			
imagejpeg($dst, $location, 100);
@imagedestroy($src);
@imagedestroy($dst);

Shouldn't it be:

imagecopyresampled($dst, $src, 0, 0, $cropX, $cropY, $cropWidth, $cropHeight, $imageWidth, $imageHeight);

if($type == "image/jpeg"){
				//create new jpeg image
				$src = imagecreatefromjpeg($location);
				$dst = imagecreatetruecolor($crop_width, $crop_height); 
				imagecopyresampled($dst, $src, 0, 0, $cropX, $cropY, $crop_width, $crop_height, $image_width, $image_height);
				imagerotate($dst, $rotate, 0);
				imagejpeg($dst, $location, 100);
				//create jpeg thumb
				$t_src = imagecreatefromjpeg($location);
			    $t_dst = imagecreatetruecolor($t_width, $t_height);
			    imagecopyresampled($t_dst, $t_src, 0, 0, 0, 0, $t_width, $t_height, $crop_width, $crop_height);
			    imagejpeg($t_dst, '../'.$uploads.'thumb_'.$imageFileName, 100);
			} else if($type == "image/gif"){
				//create new gif image
				$src = imagecreatefromgif($location);
				$dst = imagecreatetruecolor($crop_width, $crop_height); 
				imagecopyresampled($dst, $src, 0, 0, $cropX, $cropY, $crop_width, $crop_height, $image_width, $image_height);
				imagerotate($dst, $rotate, 0);
				imagegif($dst, $location, 100);
				//create gif thumb
				$t_src = imagecreatefromgif($location);
			    $t_dst = imagecreatetruecolor($t_width, $t_height);
			    imagecopyresampled($t_dst, $t_src, 0, 0, 0, 0, $t_width, $t_height, $crop_width, $crop_height);
			    imagegif($t_dst, '../'.$uploads.'thumb_'.$imageFileName, 100);
			}

I changed it around so that it could do more and now i get a few errors. It makes the correct size image just it's black, meaning it obviously didn't resample.

Warning: imagecreatetruecolor(): Invalid image dimensions

Where are the $t_height and $t_width variables ever defined?

I now get no errors, however i still have a black picture.

if($type == "image/jpeg"){
				//create new jpeg image
				$src = imagecreatefromjpeg($location);
				$dst = imagecreatetruecolor($crop_width, $crop_height); 
				imagecopyresampled($dst, $src, 0, 0, $cropX, $cropY, $crop_width, $crop_height, $image_width, $image_height);
				imagejpeg($dst, $location, 100);
				//create jpeg thumb
				$t_src = imagecreatefromjpeg($location);
			    $t_dst = imagecreatetruecolor($t_width, $t_height);
			    imagecopyresampled($t_dst, $t_src, 0, 0, 0, 0, $t_width, $t_height, $crop_width, $crop_height);
			    imagejpeg($t_dst, '../'.$uploads.'thumb_'.$imageFileName, 100);
			} else if($type == "image/gif"){
				//create new gif image
				$src = imagecreatefromgif($location);
				$dst = imagecreatetruecolor($crop_width, $crop_height); 
				imagecopyresampled($dst, $src, 0, 0, $cropX, $cropY, $crop_width, $crop_height, $image_width, $image_height);
				imagegif($dst, $location, 100);
				//create gif thumb
				$t_src = imagecreatefromgif($location);
			    $t_dst = imagecreatetruecolor($t_width, $t_height);
			    imagecopyresampled($t_dst, $t_src, 0, 0, 0, 0, $t_width, $t_height, $crop_width, $crop_height);
			    imagegif($t_dst, '../'.$uploads.'thumb_'.$imageFileName, 100);
