I want to delete previously uploaded image after updating via postman but it wont delete the previous image file.

class SocialPostController extends Controller {

/**
 * Store a newly created resource in storage.
 *
 * @param \Illuminate\Http\Request $request

 * @throws \Illuminate\Validation\ValidationException
 */
public function store(Request $request)
{
    $this->validate($request, [
        'name' => 'required|unique:social_posts,name',
        'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:3040',
        'likes_count' => 'required|numeric',
        'comment_count' => 'required|numeric',
        'url' => 'required',
        'status' => 'required|in:active,inactive',
        'sm_page_id' => 'required|numeric',


    ]);
    $name = $request->file('image')->getClientOriginalName();
    $path = $request->file('image')->storeAs('public/images', $name);

    $attribute = array_merge($request->all(), ['user_id' => Auth::id()]);
    $social_post = SocialPost::create($attribute);


    return response(['social_post' => $social_post, 'message' => 'Successful'], 200);
}

/**

 *
 * @param int $id
 * @return \Illuminate\Http\Response
 */
public function show($id)
{
    $user = SocialPost::find($id);
    return response(['social_post' => $user, 'message' => 'Successful'], 200);

}

/**

 *
 * @param \Illuminate\Http\Request $request
 * @param int $id
 * @return \Illuminate\Http\Response
 */
public function update(Request $request, SocialPost $social_post)
{

    if ($request->file('image') != '') {
        $path =storage_path('app/public/images/') .$social_post->image;

        if (File::exists($path)) {
            File::delete($path);
        }

        $name = $request->file('image')->getClientOriginalName();
        $path = $request->file('image')->storeAs('public/images', $name);

    } else {
        $name = $social_post->image;
    }

    $attribute = array_merge($request->all(), ['user_id' => Auth::id()]);


    $social_post->update($attribute);

    return response(['social_post' => $social_post, 'message' => 'Successful'], 200);
}

/**

 */
public function destroy($id)
{
    DB::table("social_posts")->where('id', $id)->delete();

    return response()->json([
        'success' => true,
        'message' => 'SocialPosts Deleted successfully.'
    ], 200);
}
