Example #1 Outputting a JPEG image to the browser
<?php // Create a blank image and add some text $im = imagecreatetruecolor(120, 20); $text_color = imagecolorallocate($im, 233, 14, 91); imagestring($im, 1, 5, 5, 'A Simple Text String', $text_color); // Set the content type header - in this case image/jpeg header('Content-Type: image/jpeg'); // Output the image imagejpeg($im); // Free up memory imagedestroy($im); ?>
