Attach images to product variants when creating a new product Laravel

i'm having difficulty attaching images to variants when creating new products. for example a product A with

variant A1
color blue
size small
images img1, img2

variant A2
color blue
size medium
image img3 img4

when I save this to the database, img1, img2, img3, img4 goes to both variant A1 and A2 instead of each variant to have its own images. How do I solve this?

here is my controller

public function variants(Request $request)
    {

        $data = $request->all();
        foreach($data['title'] as $key => $value){
          if(!empty($value)){
              $attribute = new \App\Variant;
              $attribute->title  = $value;
              $attribute->size = $data['size'][$key];
              $attribute->color = $data['color'][$key];
              $attribute->save();

              $attributeID = $attribute->id;

              if($request->hasFile('image')){

                $store_file = [];
                $files = $request->file('image');
                foreach ($files as $file) {
                    $images = $file->store('public/photos');

                    $store_file[] = [
                        'filename' =>  $images,
                        'variant_id' =>  $attributeID
                    ];
                }
                ProductsPhoto::insert($store_file);
            }
          }

        }

    }
