What are the potential pitfalls of using the rand() function in PHP for random image generation?

Using the `rand()` function in PHP for random image generation can lead to biased results as it is not truly random. To address this issue, you can use the `mt_rand()` function which generates random numbers using the Mersenne Twister algorithm, providing a more reliable source of randomness. 

// Generate a random number using mt_rand()
$randomNumber = mt_rand(1, 10);

// Use the random number to select an image
$imagePath = "image" . $randomNumber . ".jpg";

// Display the selected image
echo "<img src='$imagePath' alt='Random Image'>";
