How to display multiple images for a product in Laravel 5.8

I have 2 models. Item & ItemImage. Eloquent model relationships are defined in those models. Each item can have MANY different images, and each image can belong to only one item.

Item Model

<?php

namespace App;

use EloquentFilter\Filterable;
use Illuminate\Database\Eloquent\Model;

class Item extends Model 
{

  protected $table ='items';
  protected $primaryKey = 'id';

 public function itemphotos() 
  {
    return $this->hasMany('App\ItemImage'); 
  }

}

ItemImage model

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class ItemImage extends Model
{
    protected $table = 'itemimages';
    protected $primaryKey='id';
    protected $fillable = ['item_id', 'name'];

    public function item() {
        return $this->belongsTo('App\Item');
    }

}

My routes are set like this

Route::resource('image-gallery','ItemImageController');
  Route::resource('/item', 'ItemController');

ItemImageController

<?php

namespace App\Http\Controllers\Admin;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Http\Requests;
use DB;
use Validator;
use Redirect;
use View;
use Image;
use File;



// import the storage facade
use Illuminate\Support\Facades\Storage;

//import ItemImage model.
use App\ItemImage;

// import Item model.
use App\Item;

class ItemImageController extends Controller
{
  
    public function store(Request $request)
    {
        $request->validate([
        'images' => 'required',
        'images.*' => 'image|max:2048|mimes:jpeg,png,jpg,gif,svg'
        ]);
        
        $input = $request->all();
   

        // Gets item id from upload images form
        $item_id = $request->input('item_id');
        
        // Names of folders
        $itemimagefolder = public_path().'/itemimages/' . $item_id;
        $itemimagethumbsfolder = public_path().'/itemimages/' . $item_id . '/thumbs';

        // Makes folders for storing images and thumbs for each item if it doesn't exist. 
        // Works with 493 permission instead of 0755 on windows.
        if( ! File::exists($itemimagefolder)) {
            File::makeDirectory($itemimagefolder, 0755, true);
        }
        if( ! File::exists($itemimagethumbsfolder)) {
            File::makeDirectory($itemimagethumbsfolder, 0755, true);
        }
        
        $inputData=$request->all();
        if($request->file('images')){
            
            $images=$request->file('images');
            
            // loop through each image to save and upload
            foreach ($images as $image){
                if($image->isValid()){
                    $extension=$image->getClientOriginalExtension();
                    $filename=rand(100,999999).time().'.'.$extension;
                    
                    $large_image_path=($itemimagefolder.'/'.$filename);
                    $small_image_path=($itemimagethumbsfolder.'/'.$filename);
                    
                    // Resize Images
                    Image::make($image)->save($large_image_path);
                    Image::make($image)->resize(225,169)->save($small_image_path);
                        
                    // Passes filename to $inputData variable for database write
                    $inputData['name']=$filename;
                    
                    // writes to database via eloquent model
                    ItemImage::create($inputData);
                }
            }
        }
        
        return back()->with('status','Images added successfully.');
        
    }  
    
    public function show($id)
    {
        
        $item=Item::findOrFail($id);
        $imageGalleries=ItemImage::where('item_id',$id)->get();
        //dd($imageGalleries);
        return view('admin.itemgallery',compact('item','imageGalleries'));
    }

}

Migration for itemimages table is shown below.

 public function up()
    {
        Schema::create('itemimages', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->unsignedBigInteger('item_id');
            $table->string('name', 256);
            $table->timestamps();
            $table->foreign('item_id')
            ->references('id')->on('items')
            ->onDelete('no action')
            ->onUpdate('no action');

        });
    }

Basically, my uploading works flawlessly and images are stored properly in a public folder. I can properly display images associated with a particular item through the ItemImageController's show function. For example "http://localhost/admin/image-gallery/45" will display images of items associated with item #45.

Problem happens when I try to display images from within the ITEM controller's show function. I haven't been able to figure out how to make it work. If i copy ItemImage controller show section into item controller's show function I will get an error saying "Property [id] does not exist on this collection instance."

    public function show(Item $item)
    {
    $item=Item::findOrFail($item);
    $imageGalleries=ItemImage::where('item_id',$item)->get();
    //dd($imageGalleries);
    return view('admin.itemview',compact('item','imageGalleries'));
    }

Basically I think I didn't fully understand how to use Eloquent properly. Could someone please help me understand where my error is?

I was just able to do it but using Query builder instead. The following displays images correctly within the item controller. I'm starting to think I shouldn't waste any more time on Eloquent and develop everything with the Query builder. I know MYSQL syntax pretty well and it seems that the Query Builder offers more flexibility and it also offers better performance.

    public function show(Item $item)
    {
    // Gets a list of all images for a particular image from database.
    $imageGalleries = DB::table('itemimages')
    ->where('item_id', $item->id)
    ->get();
    return view('admin.itemview',compact('item','imageGalleries'));
    }
