Permission issue laravel 5 storeas()

So I'm using laravel on a windows 10 machine with Xampp.

I am attempting to upload files from a form to storage/app/images/ but every time I attempt to do so I'm coming up a Permission issue.

ErrorException in FilesystemAdapter.php line 119: fopen(C:\xampp\htdocs\test\public): failed to open stream: Permission denied

The function which I'm uploading the file is

     $request->file('imgurl')->storeAs('images',request()->file('imgurl')->getClientOriginalName());
return back();

Things I have done

1. Checked the file is being passed, a dd($request->getClientOriginalName()) returns the files original name
2. Checked the permissions on the storage/images folder. They are set to 755 (drwxr-xr-x 1)
3. php artisan cache:clear, chmod -R 777 app/storage, composer dump-autoload
