How can one ensure that subcategory images remain visible in a dynamic menu after navigating to a different page?

To ensure that subcategory images remain visible in a dynamic menu after navigating to a different page, you can store the selected subcategory in a session variable. This way, when the user navigates to a different page, you can use the session variable to highlight the selected subcategory in the menu. 

// Start or resume a session
session_start();

// Set the selected subcategory in a session variable
$_SESSION['selected_subcategory'] = 'subcategory1';

// Use the session variable to highlight the selected subcategory in the menu
if(isset($_SESSION['selected_subcategory']) && $_SESSION['selected_subcategory'] == 'subcategory1') {
    echo '<a href="subcategory1.php" class="selected">Subcategory 1</a>';
} else {
    echo '<a href="subcategory1.php">Subcategory 1</a>';
}
