I can't save a image in public path --Can't write image data to path --

First of all, thank you for taking your time to read my problem.

I have the following issue and I can't figure it out. I'm trying that an User will be able to upload an image when it's created. In my store method on UserController I have this

namespace App\Http\Controllers;


use Illuminate\Http\Request;
use Laracasts\Flash;
use Illuminate\Support\Facades\Auth;
use App\Http\Requests\UserRequest;
use App\UserPhoto;
use App\User;
use DB;
use Image;

/*Other methods*/

public function store(UserRequest $request)
    {
        $user = new User($request->all());
        $user->password = bcrypt($request->password);
        $user->save();

        if ($request->hasFile('photos')) {
            $user_photos = $request->file('photos');
            $last_user = User::orderBy('created_at', 'desc')->first();
            foreach ($user_photos as $user_photo) {

                $path = public_path('storage/users/photos/' . $user_photo->hashName());
                $img = Image::make($user_photo->getRealPath());

                $watermark = Image::make(public_path('storage/watermarks/MAK-50-Blanco.png'));

                $watermark->resize(150, 150, function ($constraint) {
                    $constraint->aspectRatio();
                });

                $img->insert($watermark, 'center');

                $img->resize(160, 160, function ($constraint) {
                    $constraint->aspectRatio();
                });
                
                // If I do this, i get a mkdir(): Permission denied
                
                /* if (!file_exists($path)) {
                    mkdir($path, 666, true);
                }*/


                $img->save($path);

                UserPhoto::create([
                    'name' => $user_photo->hashName(),
                    'user_id' => $last_user->id
                ]);
            }

        }

        flash('user created sucessfully')->success();
        return redirect('/users');
    }

An then, when I sumbit the form, this error jumps

Can't write image data to path
(/home/mito/PhpstormProjects/makpropiedades/public/storage/users/photos/Wr3kbBukXu9FEbjlYncBo2rmImpelRnY4Xgd8DYi.jpeg)
>>> in Image.php (line 143)
at Image->save('/home/mito/PhpstormProjects/makpropiedades/public/storage/users/photos/Wr3kbBukXu9FEbjlYncBo2rmImpelRnY4Xgd8DYi.jpeg')

>>> in UserController.php (line 79)

I thought when you code img->save($imgPath) this will create the folders if they're not created. Also, I've tried to sudo chmod -R app/public/storage but the same error again.

I also did

php artisan storage:link

I was following this tutorial

I don't know what to do. Please help :(
