Issue passing files (photos) to command bus

Evening everyone,

I'm currently diving into Commands and I've hit a bit of a brick wall. I can't seem to pass my files (photos) to my command.

So, I have an AdminPhotosController that currently deals with the PhotoRequest, creating a thumbnail, uploading to S3 and persisting some details to the database. Of course, this isn't ideal.

I followed Taylors screencast which showed an example of passing a Request to the command itself, so here's my store method on my AdminPhotosController;

public function store(PhotoRequest $request)
{
    $this->dispatchFrom(AddPhotoCommand::class, $request);

    return redirect()->route('admin.photos.index');
}

Note: The PhotoRequest doesn't have any validation rules for now so that's not the issue.

Now, here's my AddPhotoCommand;

class AddPhotoCommand extends Command implements SelfHandling, ShouldBeQueued {

    use InteractsWithQueue, SerializesModels;

    protected $female_id, $photos;

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct($female_id, $photos)
    {
        $this->female_id = $female_id;
        $this->photos = $photos;
    }

    /**
     * Execute the command.
     *
     * @return void
     */
    public function handle()
    {

        foreach($this->photos as $photo) {

            /* ------------------------------------
            #. Generate Thumb
            ------------------------------------ */
            $thumbnail = Image::make($photo->getRealPath());
            $thumbnail->fit(300)->save(public_path('temp/').$photo->getClientOriginalName());

            /* ------------------------------------
            #. Random String for File
            ------------------------------------ */
            $str = str_random(10).'-';

            /* ------------------------------------
            #. Target Paths
            ------------------------------------ */
            $path       = s3_female_path($this->female_id).$str.$photo->getClientOriginalName().'';
            $thumb_path = s3_female_thumb_path($request->input('female_id', true)).$str.$photo->getClientOriginalName().'';

            /* ------------------------------------
            #. Put to S3
            ------------------------------------ */
            $disk = Storage::disk('s3'); // Mount Disk

            $disk->put($path, file_get_contents($photo)); // Full Image
            $disk->put($thumb_path, $thumbnail); // Thumbnail

            /* ------------------------------------
            #. Persist
            ------------------------------------ */
            $photo = Photo::create([
                'female_id' => $this->female_id,
                'path'      => s3_file_path($path),
                'thumb_path'=> s3_file_path($thumb_path),
                'size'      => $photo->getSize()
            ]);

        }
    }
}

When submitting my form, I receive the following error;

ErrorException in AddPhotoCommand.php line 37:
Invalid argument supplied for foreach()

So what I then did, was die and dump $this->photos which for some odd reason is returning null.

I then proceeded to attempt a die and dump on $this->female_id - which returned the id successfully, so my Request is making it's way through - but I can't seem to access my the photos?

Any help would be appreciated!
