Php. Как вставить фото в генератор?

PHP:

1. <?php
2. error_reporting(0);
3. $key = $_GET['q'];
4. if ($key == '') {
5. //$key = urlencode('test');
6. //print ' ';
7. }
8. ?>
9. <?php
10. $q2 = $key;
11. $q2s = str_replace('+', ' ', $q2s);
12. session_start();
13.  
14. //You can do any necessary settings as you wish here
15. //If you reduce the width and height of the captcha here then you have to change it in the css file as well
16. $image_width = 600;
17. $image_height = 500;
18. $characters_on_image = 10;
19. $font = 'images/monofont.ttf';
20.  
21. //The characters that can be used in the CAPTCHA code. Avoid confusing characters (l 1 and i for example)
22. $possible_letters = "".$key."";
23. $random_dots = 0;
24. $random_lines = 20;
25. $random_imgs = 1;
26. $captcha_text_color="0x142864";
27. $captcha_noice_color = "0x142864";
28.  
29. $code = '';
30. $code = $key;
31. //$i = 0;
32. //while ($i < $characters_on_image)
33. //{
34. //    $code .= substr($possible_letters, mt_rand(0, strlen($possible_letters)-1), 1);
35. //    $i++;
36. //}
37. $font_size = $image_height * 0.04;
38. $image = @imagecreate($image_width, $image_height);
39.  
40.  
41. /*Setting the background, text and noise colours here */
42. $background_color = imagecolorallocate($image, 255, 255, 255);
43.  
44. $arr_text_color = RGB_HEX($captcha_text_color);

50.

52. for( $i=0; $i<$random_dots; $i++ )
53. {
54.     imagefilledellipse($image, mt_rand(0,$image_width),
55.      mt_rand(0,$image_height), 2, 3, $image_noise_color);
56. }
57.  
58.

81. imagettftext($image, $font_size, 0, $x, $y, $text_color, $font , $code);
82.  
83. /* Show captcha image in the page html page */
84. header('Content-Type: image/jpeg');// defining the image type to be shown in browser widow
85. imagejpeg($image);//showing the image
86. imagedestroy($image);//destroying the image instance

88.  
89. function RGB_HEX ($hexstr)

93. }
94. ?>

Получается так

P.S. Хочу чтобы за место круга грузилось рандомное фото из папки.
Пожалуйста помогите реализовать - очень надо.

 

Ерунда какая-то! Еще может варианты будут внедренные в код... Я же помощи прошу! =)

 

поможет кто нить?
