What are common pitfalls when trying to download images using PHP and how can they be avoided?

Common pitfalls when trying to download images using PHP include not properly setting the headers for the image file, not handling errors correctly, and not sanitizing user input. To avoid these pitfalls, make sure to set the correct headers, handle errors gracefully, and validate user input to prevent security vulnerabilities. 

// Set headers for image file
header('Content-Type: image/jpeg');
header('Content-Disposition: attachment; filename="image.jpg"');

// Download image file
$image_url = 'https://example.com/image.jpg';
$image_data = file_get_contents($image_url);
echo $image_data;
