What potential issues might arise when implementing a random avatar script in PHP?

One potential issue that might arise when implementing a random avatar script in PHP is that the script may not be able to locate the avatar images if the file paths are incorrect or if the images are not properly stored in the designated directory. To solve this issue, it is important to ensure that the file paths are accurate and that the avatar images are stored in the correct directory. 

// Ensure that the file paths are correct and that the avatar images are stored in the designated directory
$avatarDirectory = 'avatars/';
$avatarImages = glob($avatarDirectory . '*.{jpg,png,gif}', GLOB_BRACE);

// Check if avatar images are found
if (empty($avatarImages)) {
    echo 'No avatar images found in the specified directory';
} else {
    // Randomly select an avatar image
    $randomAvatar = $avatarImages[array_rand($avatarImages)];
    echo '<img src="' . $randomAvatar . '" alt="Random Avatar">';
}
