What potential issues can arise when trying to generate thumbnails in PHP on a Windows server compared to a Linux server?

One potential issue when generating thumbnails in PHP on a Windows server compared to a Linux server is the difference in file path handling. Windows uses backslashes (\) in file paths while Linux uses forward slashes (/). To ensure cross-platform compatibility, you can use the `DIRECTORY_SEPARATOR` constant in PHP to dynamically generate file paths. 

// Define the directory separator based on the server's operating system
define('DS', DIRECTORY_SEPARATOR);

// Example usage to generate a thumbnail file path
$thumbnailPath = 'thumbnails' . DS . 'image.jpg';
