How to change the mark when there is no image (I want to change it to text)

"For example, when there is no image, such as """" or ""replacement text"" when a user does not post an image."
I'm thinking about using text this time because the image might be heavy.

I'm in trouble because I can't find a reference article because I'm not stuck in the search.
I think it will be displayed after conditional branching and setting the return value in return...

PostsController.php

/**
     * Post Listing Action
     */
    public function index (Request$request)
    {
        $searchword=$request->searchword;

        $posts=Post::with(['comments','category'])#Query Adjustment
            ->orderBy('created_at','desc')
            ->fuzzyNameMessage($searchword)
            ->paginate(10); 
        
        US>return view('bbs.index',[ 
            'posts' = > $posts,
            'searchword' = > $searchword
        ]);
    }

    /**
    * Learn More
    */
    public function show (Request $request, $id)
    {
        $user=auth()->user();
        $post=Post::findOrFail($id);

        return view('bbs.show', compact('post'));
    }

index.blade.php

@foreach($posts as$post)
            <tr>
                <td>{{optional($post)->id}}</td>
                <td>{{optional($post->created_at)->format('Y.m.d')}}</td>
                <td>{{$post->user->name}}</td>
                <td>{{optional($post)->subject}}</td>
                <td><img src="{asset('/storage/'.$post->image_file)}}" width="150px">/td>
                <td>{!!nl2br(e(Str::limit($post->message,100)))!!}
                @ if($post->comments->count()>=1)
                    <p><span class="badge badge-primary">Comments: {{optional($post->comments)->count()}}} cases</span></p>
                @endif
                </td>
                <td class="text-nowrap">
                    <p><a href="{ action('PostsController@show', $post->id)}}" class="btn btn-primary btn-sm">Learn more</a>>/p>
                    @can('edit',$post)
                        <p><a href="{ action('PostsController@edit', $post->id)}}" class="btn btn-info btn-sm">Edit<a>>/p>
                        <p>
                            <form method="POST" action="{action('PostsController@destroy', $post->id)}}">
                                @csrf
                                @method('DELETE')
                                <button class="btn btn-danger btn-sm">Delete </button>
                            </form>
                        </p>
                    @endcan
                </td>
            </tr>
        @endforeach

$post->image_file answers assuming it contains the image path

If the image_file is empty (or NULL) in View, it is good to display alternative text.

index.blade.php

{--omitted--}}
<td>{{optional($post)->subject}}</td>
<td>
  @ if(empty($post->image_file))
    No image
  @else
    <img src="{{asset('/storage/'.$post->image_file)}}"width="150px">
  @endif
</td>
<td>{!!nl2br(e(Str::limit($post->message,100)))!!}
{{-- Omitted --}}
