What are some common reasons for PHP not displaying an image when using imagecreatefromjpeg() and imagejpeg() functions?

One common reason for PHP not displaying an image when using imagecreatefromjpeg() and imagejpeg() functions is incorrect file paths. Make sure that the file path provided to imagecreatefromjpeg() is correct and that the file exists. Additionally, check for any errors in the PHP error log that may provide more information on why the image is not being displayed. 

// Example code snippet to display an image using imagecreatefromjpeg() and imagejpeg()

// Define the file path to the image
$imagePath = 'path/to/your/image.jpg';

// Check if the file exists
if (file_exists($imagePath)) {
    // Create a new image resource from the JPEG file
    $image = imagecreatefromjpeg($imagePath);

    // Output the image to the browser
    header('Content-Type: image/jpeg');
    imagejpeg($image);

    // Free up memory
    imagedestroy($image);
} else {
    echo 'Image file not found.';
}
