How can PHP scripts be used to display images with appropriate permissions, such as for specific user groups, without compromising security?

To display images with appropriate permissions for specific user groups in PHP, you can store the images outside the web root directory and use PHP scripts to serve the images based on user permissions. By checking the user's permissions before serving the image, you can ensure that only authorized users can view the image without compromising security. 

<?php
// Check user permissions here, for example:
$userGroup = 'admin';

// Define the path to the images directory outside the web root
$imagePath = '/path/to/images/';

// Get the image file name from the request
$imageName = $_GET['image'];

// Check if the user has permission to view the image
if ($userGroup === 'admin') {
    // Serve the image if the user has permission
    $image = $imagePath . $imageName;
    header('Content-Type: image/jpeg');
    readfile($image);
} else {
    // Display an error message or redirect to a different page
    echo 'You do not have permission to view this image.';
}
?>
