captcha.php

Paspēlējos ar blogiem.lv captcha ;)
Diez ko tālu netiku:

<?php
$bilde='captcha.png';
$i=imagecreatefrompng($bilde);
$dx=imagesx($i);
$dy=imagesy($i);
for($y=0;$y<$dy;$y++){
for($x=0;$x<$dx;$x++){
$c=imagecolorat($i,$x,$y);
$rgb=imagecolorsforindex($i,$c);
$a=$rgb['red']+$rgb['green']+$rgb['blue'];
if($a<383){
$b='<strong>0</strong>';
}else{
$b='0';
}
echo $b;
}
echo'<br />';
}
imagedestroy($i);
?>
