How can PHP developers troubleshoot image display issues in their code?

To troubleshoot image display issues in PHP code, developers can check if the image path is correct, ensure the image file exists on the server, and verify permissions are set correctly. They can also use PHP functions like file_exists() and is_readable() to confirm the image file can be accessed. 

$image_path = 'path/to/image.jpg';

if (file_exists($image_path) && is_readable($image_path)) {
    echo '<img src="' . $image_path . '" alt="Image">';
} else {
    echo 'Image not found or inaccessible.';
}
