How could the code be optimized to ensure that the next image in the gallery is selected correctly?

The issue can be resolved by ensuring that the index for the next image in the gallery is within the bounds of the array. This can be achieved by checking if the current index is less than the total number of images in the gallery before selecting the next image. 

// Ensure that the next image index is within bounds
if ($current_index + 1 < count($gallery_images)) {
    $next_image = $gallery_images[$current_index + 1];
} else {
    $next_image = $gallery_images[0]; // Loop back to the first image
}
