First, please make sure you've activated "Random Image Validation" option in admin. Please see all places where it could be activated here:
http://www.viart.com/spam_alert_how_to_ptotect_your_shop.html
If you see an empty space instead of captcha it could be a problem with fonts. We recommend to open the script "validation_image.php" and replace this line:
if (function_exists("imagettftext")) {
with this one:
if (function_exists("imagettftext") && false) {
Then only numbers will be used for captcha.
If it doesn't work as well then most likely the validation image is not displayed because GD library is not activated in the php settings on your server. Contact your hosting provider and ask them to install it for you.
