How can PHP developers troubleshoot and fix issues with image display in a PHP slideshow script?

Issue: PHP developers can troubleshoot and fix issues with image display in a PHP slideshow script by checking the file paths of the images, ensuring that the images exist in the specified directories, and verifying that the image file formats are supported by the script.

// Check the file path of the images
$image_path = "images/image1.jpg";
if (file_exists($image_path)) {
    // Display the image in the slideshow
    echo "<img src='$image_path' alt='Image 1'>";
} else {
    echo "Image not found.";
}
