[BlueOnyx:19873] Re: GD image problem

[fastreplies]

Hello Michael,

We have added  /usr/bin/ to OpenBasedir vsites and servers but to no avail 
the problem is still there

As to referring to gd.php script code that is not working but was working 
before we have moved to new server and 5209R
-------------------------
<?php
//check to see if security code feature is on
if ($usesecuritycode == "true") {
$randcode = mt_rand(100000, 999999);
$randcodesec = base64_encode($randcode);
?>
Type the code you see on the image below
<input type="text" name="userSecurityCode" maxlength="6" size="8">
<input type="hidden" name="SecurityCode" value="<?php echo $randcodesec; ?>" 
/>
<img src="gd.php?randcode=<?php echo $randcodesec; ?>" alt="Security Code" 
/>
<?php } ?>
--------------------------

You can see form example here http://www.amray.com/form/mform.php

Cheers
Bart
