I tried using a foreach loop to iterate through the request files, but only the last image in the loop is saved to the database and file system. How can I fix this? any help would be appreciated,
here is my code

$galleryArr = []; 
$allowedExtensions = ['jpg', 'png', 'jpeg']; 
$counter = 1;

if ($req->hasFile('images')) {
  foreach ($req->file('images') as $file) {
    $fileExtension = $file->getClientOriginalExtension();
    $fileName = $currentTimestamp . "_" . $counter . "." . $fileExtension;
    // Handle thumbnail creation
    $this->generateProductThumbnailImage($file, $fileName);
    // Add to gallery array
    $galleryArr[] = $fileName;
    $counter++;
  }
}

// Convert gallery array to comma-separated string
$products->images = implode(',', $galleryArr);

// Save the product data
$products->save();

public function GenerateProductThumbnailImage($image, $imageName) {
  $destinationPathThumbnail = public_path('img/prod/thumbnail');
  $destinationPath = public_path('img/prod');
  $img = Image::make($image->path());

  // Save the original image
  $img->resize(540, 689, function($constraint) { $constraint->aspectRatio(); })->save($destinationPath . "https://stackoverflow.com/" . $imageName);

  // Save the thumbnail image
  $img->resize(104, 104, function($constraint) { $constraint->aspectRatio(); })->save($destinationPathThumbnail . "https://stackoverflow.com/" . $imageName);
}
