I haven't been unkind to you.

[TcM]

I didn't say you are unkind to me... you are just annoying sometimes.

Anyways, we went completely off-topic. We already discussed this via PM (sorta) so let's just continue with our lives...

It seems to imply that you want me to be kinder first. But it doesn't matter, I'm tired of arguing. Truce?

[TcM]

IMO a few weeks ago we were going along quite good. Let's just continue that way..

[Xav]

It was just when you said the stuff about IM in the chat thread, it dampened my spirits a bit.

OK, Arguing Locked. Lol

Let's try it

i was wondering about ways to make ur script more random.......and i came up with the following one

PHP Code:

//FONTS TO BE USED
$font1 = 'TRASHED.ttf';
$font2 = 'trashco.ttf';
$font3 = 'ChalkboardBold.ttf';
$font4 = 'CHILLER.TTF';
$fonts = array($font1, $font2, $font3, $font4);

//IMAGES TO BE USED
$image1 = 'image.jpg';
$image2 = 'image (1).jpg';
$image3 = 'image (2).jpg';
$image4 = 'image (3).jpg';
$image5 = 'image (4).jpg';
$image6 = 'image (5).jpg';
$images = array($image1, $image2, $image3, $image4, $image5, $image6);



session_start();

//background image randomization
shuffle($images);
$im = imagecreatefromjpeg ($images[0]);
    if ( function_exists( 'imagefilter' ) )
        {
            imagefilter( $im, IMG_FILTER_GAUSSIAN_BLUR );
        }
        
$g2 = rand(1, 10);
    if($g2 < 5){
        $gaussian = array(array(1.0, 2.0, 1.0), array(2.0, 4.0, 2.0), array(1.0, 2.0, 1.0));
        imageconvolution($im, $gaussian, 16, 0);
        }
        
    if($gd2 > 5){
        imagefilter($im, IMG_FILTER_GRAYSCALE, 100);
        }

$rand1 = rand(1,255);
$rand2 = rand(1,255);
$rand3 = rand(1,255);
$color = imagecolorallocate($im, $rand1, $rand2, $rand3);

$_direction = ( time() % 2 ) ? TRUE : FALSE;

        

//smart 'readable word' creation :P
$no2 = rand(1, 10);

if ($no2 == 10) {
    $str = str_shuffle(ao);
}
if ($no2 == 1) {
    $str = str_shuffle(da);
}
if ($no2 == 2) {
    $str = str_shuffle(ge);
}
if ($no2 == 3) {
    $str = str_shuffle(ji);
}
if ($no2 == 4) {
    $str = str_shuffle(mo);
}
if ($no2 == 5) {
    $str = str_shuffle(pu);
}
if ($no2 == 6) {
    $str = str_shuffle(sa);
}
if ($no2 == 7) {
    $str = str_shuffle(vi);
}
if ($no2 == 8) {
    $str = str_shuffle(xe);
}
if ($no2 == 9) {
    $str = str_shuffle(io);
}

$str1 = array(a, e, i, o, u);
shuffle($str1);

$str2 = array(a, b, c, d, f, g, j, k, l, m, n, p, q, r, s, t, x, z);
shuffle($str2);

$text = $str.$str1[0].$str2[0];

//font randomization
shuffle($fonts);
$font = $fonts[0];

//text size and offset randomization
$size = rand(30, 40);
$off = rand(0, 50);

//image creation
imagettftext($im, $size, 0, $off, 45, $color, $font, $text);
header('Content-type: image/jpg');
imagejpeg($im);
imagedestroy($im);


$_SESSION['captcha'] = $text;
?>

hmm.. looks cool mate nice job..

thanks bro,

[maix]

i would really appreciate if someone write some kind of code that will pick out the fonts and images automatically without us having to define the variables manually ...............that would make the script some what user friendly...............................
