Opinions about using Storage inside a controller

Hello everyone, I was just working on a project and I am handling an image upload/Update situation for a post inside my Posts Controller.

My question is mostly about if it's "okay" or not using Storage inside my controller or make a helper class to handle this situation

This is my update function inside my PostsController

 protected function update(array $data, $id)
{   
    $post = Post::findOrFail($id);
    
    if (isset($data['image'])) {

        if (Storage::disk('public')->exists($post->image)) {
            Storage::disk('public')->delete($post->image);
        };

        $image = $this->uploadImage($data['image']);

        unset($data['image']);

        $data = $data + $image;
        
    }

    $post->update($data);
    
    return response()->json([
        'updated' => true
    ]);
}

This is the UploadImage function inside my PostsController

 protected function uploadImage($image)
{   
    return [
        'image' => $image->storeAs('posts', $image->getClientOriginalName(), 'public')
    ];
}

Everything is built with TDD and is working as expected, just more of an opinion situation.
