* Enabled:
When enabled, visitors must recognize a graphic image to show that they are real visitors (and not spam bots). If this option is disabled, the graphic code image will not be displayed on the comment form. We strongly recommend that you enable the graphic code protection feature as it protects from automated spam entries in your Guestbook. Note that visitors can use the "Preview" feature without recognizing the graphic image.
Default value: Enabled
* Password Pattern:
This pattern defines the set of characters that can be used in the graphic code image. The pattern is a standard regular expression, note the brackets at the begin and at the end. Only upper-case characters are accepted, lower-case characters will automatically be converted to their respective upper-case equivalents. For example, if you want to allow the characters A to Z and the numbers 0 to 9, you have to use the following password pattern:
[A-Z0-9]
We recommend that you use numbers only in your image code, as they are easier to recognize by humans. The default value for this field consists of the numbers from 0 to 9.
Default value: [1234567890]
* Password Length:
This number defines how many characters your image protection will have. The characters used for the image text are defined by the "Password
Pattern" field.
Default value: 5
* Image Height in Pixels:
This number defines the height of the protection image. Adjust it for your custom design if needed.
