foreach file image directory Laravel - php

Question

I'm learning how to use Laravel. I just learned how to do a foreach loop in my database for articles. Now I want to try the same but loop for all the images in my image directory. How can I do this? Is it similar to this :
#foreach (File::allFiles(public_path().'/assets/image/') as $file)
{
$filename = $file->getRelativePathName();
echo HTML::image('public/assets/img/'.$filename, $filename);
}
#endforeach
also in my article page I was able to apply the foreach to a li object, how can I do the same for my images?
#foreach($articles as $article)
<div class="grid-item">
<li>{{$article->photo}}</li>
<li>{{$article->title}}</li>
{!! Form::open(['url' => 'article' ]) !!}
{!! Form::file('image', null) !!}
<div class="form-group">
{!! Form::hidden('user_id', $article->user_id, ['class' => 'form-control']) !!}
</div>
<div class="form-group">
{!! Form::submit('Like', ['class' => 'btn btn-primary form-control']) !!}
</div>
</div>
{!! Form::close() !!}
<!--{!! Form::open(['url' => 'article' ]) !!}
<div class="form-group">
{!! Form::submit('like', ['class' => 'btn btn-primary form-control']) !!}
</div>
{!! Form::close() !!}
<img href="#popup" data-toggle="modal" class="grid-item1" src="/assets/image/article/thumbnail/{{$article->photo}}">
-->
#endforeach
