CodeIgniter image upload and resize failing

Question

I am really struggling with my CodeIgniter script for uploading, resizing and cropping profile images for users. In the end, I want to upload the image with an encrypted name, resize it and save it twice (once as a thumbnail and once as a medium sized image), and then delete the original file. However, I guess I'm really missing something, because I can't get the first upload resize process to work. I definitely have an error somewhere in the code (error to follow code), but I think I may have a gap in my understanding of the logic here. Who knows? Any feedback is extremely appreciated .

public function image() {
    $config['upload_path'] = './temp_images/'; // This directory has 777 access
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size'] = '2048';
    $config['max_width']  = '0'; // For unlimited width
    $config['max_height']  = '0'; // For unlimited height
    $config['encrypt_name'] = TRUE;
    $config['remove_spaces'] = TRUE;

    $this->load->library('upload', $config);

    if ( ! $this->upload->do_upload())
    {
        $data['error'] = array('error' => $this->upload->display_errors());
        $this->load->view('upload', $data);
    }
    else
    {
        $image_data_array = array('upload_data' => $this->upload->data());
        foreach ($image_data_array as $image_data){
            $raw_name = $image_data['raw_name'];
            $file_ext = $image_data['file_ext'];
        }

        $file_name = $raw_name . $file_ext;
        $image_path = 'temp_images/' . $file_name;
        $new_path = 'image/profile/'; // This directory has 777 access

        $config['image_library'] = 'gd';
        $config['source_image'] = $image_path;
        $config['new_image'] = $new_path;
        $config['maintain_ratio'] = FALSE;
        $config['width']     = 140;
        $config['height']   = 140;
        $config['quality'] = '80%'; 

        $new_name = $new_path . $raw_name . $file_ext;

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

        // The following is just to test that it worked:

        if ( ! $this->image_lib->resize()) { 
            echo $this->image_lib->display_errors();
            echo 'source: ' . $config['source_image'] . '<br />';
            echo 'new: ' . $config['new_image'] . '<br />';
        }
        else {
            echo "<img src='" . base_url() . $new_name . "' />";
        }

        $this->image_lib->clear();

    }
}

The upload process works fine. Even the resizing worked when I just called $this->image_lib->resize(). It was when I tried the error-catching that it started yelling at me. I double-verified that both of the temp_images and image/profile have 777 permissions (as aforementioned, the upload and resize actually worked at one point). Here is the error produced:

Unable to save the image. Please make sure the image and file directory are writable.
source: temp_images/8ee1bab383cf941f34218f7535d5c078.jpg
new: image/profile/

When creating the image in 140x140 the $config['new_image'] must be the full path of the image including file name, "image/profile/$filename". $filename being something like "image.jpg" — user2844810

Never really used CI before and can't see the details of your code.

First, check the permission that set on the folder - you are trying to upload to. Also try to use the full server path.
Second, see if you have PHP image extensions such as GD, ImageMagick enabled.

Please update the new_image value by including the filename also.

$config['new_image'] = 'image/profile/' . $filename;
