<?php
if u see the source from this ,it will display the txt of that mail
?>
<img src="createimageforemail.php?email=ragiquemohamad@gmail.com">	with this it will convert that to image
<!--<img src="createimageforemail.php?email=ragiquemohamad@gmail.com"> -->
to not display in source also, we have to load from database
$email = '' means nothing	nothing between two '  and ;
no email found
we converted that email to image because of hacking, if u see source ,it will be visible, how can we avoid
if we laods from data base, nobody cant see,its safe version
<?Php
header ('content-type: image/jpeg');	sample text, same like before
//$email= 'sfd@gmail.com';
//$email =$_GET ['email'];
//in url after domain name ?email= narayana@gmail.com,it will take that and print as image ,it is called dynamic way
if (isset ($_GET['email'])){
$email = $_GET['email'];
if(!empty($email)){
$email = 'no email found';
}
else {
$email = 'no email founddd';
}
$email_length = strlen ($email);
$fsize = 4;
$img_height = ImageFontHeight($fsize) * $email_length/10;
$img_width = ImageFontWidth($fsize)* $email_length;
$image = imagecreate($img_width, $img_height);
$bg = imagecolorallocate($image, 255,255,255);
$fcolor = imagecolorallocate($image, 0,0,0);
imagestring($image, $fsize, 7 , 0, $email, $fcolor);
imagejpeg($image);
imagedestroy($image);
