What are the potential risks of exposing file paths and names in PHP when creating image puzzles?

Exposing file paths and names in PHP when creating image puzzles can pose a security risk by revealing sensitive information about the server's directory structure. To mitigate this risk, it is recommended to obscure the file paths and names by using a combination of hashing and randomization techniques. 

<?php
// Generate a random filename for the image puzzle
$random_filename = md5(uniqid(rand(), true)) . '.jpg';

// Save the image puzzle with the random filename
imagejpeg($image_puzzle, 'path/to/save/' . $random_filename);

// Display the image puzzle without revealing the actual file path
echo '<img src="path/to/save/' . $random_filename . '" alt="Image Puzzle">';
?>
