Upload multiple images for preview

Are you going to have a fixed number of images on your homepage? Or will it be variable?

it will be fix number up to 10, but wondering too how if it is not fixed number

In that case I would create a dedicated model and table for the Previews.

Here's a adapted/simplified version of what I recently did in one of my projects:

Model:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\Storage;

class Preview extends Model
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'unique_filename', 'original_filename', 'size', 'mime_type',
    ];

    /**
     * Boot the model.
     *
     * @return void
     */
    public static function boot()
    {
        parent::boot();

        self::deleting(function(Preview $preview) {
            $filePath = $preview->getFilePath();

            if (Storage::exists($filePath)) {
                Storage::delete($filePath);
            }
        });
    }

    /**
     * Get the preview's file path.
     *
     * @return string
     */
    public function getFilePath()
    {
        return sprintf("previews/%s",
            $this->unique_filename
        );
    }
}

Migration:

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreatePreviewsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('previews', function (Blueprint $table) {
            $table->id();
            $table->string('unique_filename')->unique();
            $table->text('original_filename');
            $table->bigInteger('size')->unsigned();
            $table->string('mime_type');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        //
    }
}

Let me know if you need help implementing the upload functionality.
