Hello

Make sure your server has gd libraries enabled. you can check this by using this small script.
<?php
header(\"Content-type: image/png\"«»);
$im = @imagecreate(110, 20)
    or die(\"Cannot Initialize new GD image stream\"«»);
$background_color = imagecolorallocate($im, 0, 0, 0);
$text_color = imagecolorallocate($im, 119, 255, 111);
imagestring($im, 1, 5, 5,  \"GD Found\", $text_color);
imagepng($im);
imagedestroy($im);
?>

Seeing the server setting seems that GD libraries are enabled, but the problem remain... Here is a link to the form.. lnx.salsamarchestyle.com/index.php?option=com_forme&fid=1 (the captcha field is named \"codice antispam\")

I tried the script but i receive an internal server error... :pinch:

My Gd configuration:

gd
GD Support enabled
GD Version bundled (2.0.28 compatible)
FreeType Support enabled
FreeType Linkage with freetype
T1Lib Support enabled
GIF Read Support enabled
GIF Create Support enabled
JPG Support enabled
PNG Support enabled
WBMP Support enabled
XBM Support enabled

If you see my guestbook here captcha works... :S

I too have a problem with captcha. My server is Linux Gentoo with gd installed. I must admit to not completely understanding how to implement this field using the supplied fields. Perhaps I just have something wrong in the field.

Help!

seems like captcha on some servers does not work because of session issues. I will fix it next week.

Hi,
Since moving to a new server my captcha field no longer show an image. You can see it here:

www.mississaugamontessori.com/index.php?...;id=15&Itemid=27

I've checked my phpinfo and it shows that the gd library is installed. See here:
gd
GD Support enabled
GD Version bundled (2.0.28 compatible)
GIF Read Support enabled
GIF Create Support enabled
JPG Support enabled
PNG Support enabled
WBMP Support enabled
XBM Support enabled

Is there something else I can check to get this working?
Thank you Tracy
