Laravel make arguments optional in a File - php

Question

<div class="images section clearfix">
<h4>Images</h4>
{!! Form::_image("image_id", "Logo", (isset($_tournament))? $_tournament->logo : null) !!}
{!! Form::_image("image_large_id", "Large Logo", (isset($_tournament))? $_tournament->logoLarge : null) !!}
{!! Form::_image("image_square_id", "Square Logo", (isset($_tournament))? $_tournament->logoSquare : null) !!}
#endif
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-6">
<p>
{!! Form::hidden($name, null, ["id" => $name]) !!}
#if(isset($image))
<img width=100 id="{{ $name }}" src="{!! staticFileUrl('img', imagePath($image->folder, $image->filename)) !!}" />
#else
<img width=100 id="{{ $name }}" src="" />
#endif
</p>
<p>
<button type="button" class="btn btn-default" data-toggle="modal" data-target="#media_select" data-fieldname="{{ $name }}">Select {{ $display_name }}</button>
<button type="button" class="btn btn-default" id="clear-media">Clear {{ $display_name }}</button>
</p>
</div>
</div>
<script type="text/javascript">
$("button#clear-media").click(function() {
$form_element = $(this).parents("div.form-group");
$form_element.find("input#{{ $name }}").val(null);
$form_element.find("img#{{ $name }}").attr("src", "");
});
</script>
I got a thrown into a laravel project and I have no experience in PHP so I have no idea to fix this.
I need to add a default image for these fields and I just wonder is there a way to make all arguments optional staticFileUrl('img', imagePath($image->folder, $image->filename) optional so I can write something like this staticFileUrl('img', imagePath("random string", "other random string")?

Those already are variables based on the values set in the $image model.
If all you need is a default, change the #else
#if(isset($image))
<img width="100" id="{{ $name }}" src="{!! staticFileUrl('img', imagePath($image->folder, $image->filename)) !!}" />
#else
<img width="100" id="{{ $name }}" src="http://www.example.org/your-image.jpg" />
#endif
It currently displays nothing if there is no image object. Adding the src and an image will display that as your default unless it has an image.
