image resize rotates images

hi all, i have a website were users can upload their photos. but the problem is the images will be resized but also rotated. i dont want this functionality. when i try it locally it works without a problem. doesnt rotate (win10). but when i try it on live site it rotates. could be a linux hosting problem ?

any ideas why this happens ? any solutions ?

here you can see my code:

PHP Code:

$data = $this->upload->data();
            
            $img_url = $data['file_name'];

            $this->load->library('image_lib');

            $config_res['source_image'] = './assets/user_uploads/' . $img_url;
            $config_res['maintain_ratio'] = TRUE;
            $config_res['width'] = 1024;
            $config_res['height'] = 768;


            $this->image_lib->initialize($config_res);

            $this->image_lib->resize();

            $this->image_lib->clear(); 


this is really important to me. any ideas ? i am considering changing the framework

Are you sure it's not EXIF data on the image itself?
