PHP Imagejpeg function - php

Question

I am using php and js for uploading images to a folder. I installed XAMPP and everything worked in localhost. Later, I uploaded my code to a server, changed the paths but it does not work.
I checked the paths in my error.log file and they are OK, also made permissions to 777 and this is the error that it shows:
"PHP Warning: imagejpeg(): Unable to open './uploads/Cartas/imagen_5923239258.jpg' for writing: No such file or directory in /ImageUploader/processupload.php on line 152"
My line 152 is the next one:
imagejpeg($source, $destination, $quality); return true;
My php code is here:
<?php
include '../php/connectionData.php';
$mytype=$_REQUEST['type'];
$updating=$_REQUEST['edit'];
global $image_save_folder;
############ Configuration ##############
$thumb_square_size = 200; //Thumbnails will be cropped to 200x200 pixels
$max_image_size = 500; //Maximum image size (height and width)
$thumb_prefix = "thumb_"; //Normal thumb Prefix
$destination_folder = './ImageUploader/uploads/'.$mytype."/";
//$destination_folder = 'C:/xampp/htdocs/pfc/ImageUploader/uploads/'.$mytype."/"; //old working directory in
$jpeg_quality = 90; //jpeg quality
