Images not displaying on webpage.

I want to make an image upload on my Laravel project, the form is submitting and the image is getting saved in the Public folder but the file name, for example, is 20210128142507.png, but displayed in the database is /tmp/phpf4WMIx

Controller:

public function store(Request $request)
    {
        $validateData = $request->validate([
            'title' => 'required',
            'user_id' => 'reqired',
            'hours' => 'required',
            'category' => 'required',
            'minutes' => 'required',
            'recipe' => 'required',
            'post' => 'required',
            'image' => 'mimes:jpg,png,jpeg',
    
           ]);

           $imageName = date('YmdHis') .'.'. $request->image->getClientOriginalExtension();
           $request->image->move(public_path('image'), $imageName);
           $insert['image'] = '$imageName';
    

    
           $validateData['user_id'] = Auth::user()->id;
           
           Blog::create($validateData);
           
           
    
           return redirect('blogs');

    }

Migration

public function up()
    {
        Schema::create('blogs', function (Blueprint $table) {
            $table->id();
            $table->text('title');
            $table->integer('user_id')->unsigned();
            $table->text('category');
            $table->integer('hours');
            $table->integer('minutes');
            $table->text('recipe');
            $table->text('post');
            $table->string('image')->nullable();
            $table->timestamps();

            
        });


    }

If anyone could help that would be greatly appreiated.
