Random words or letters that are displayed in a distorted fashion so that they can be deciphered by people, but not by software. Users are asked to type in what they see on screen to verify they are human and not a web bot.

CAPTCHA stands for "Completely Automated Public Turing test to tell Computers and Humans Apart." It is a type of challenge-response test used to determine whether a user is human. This is done by asking a user to solve a challenge that is hard for computers, but relatively easy for human beings. Mollom currently supports both image and audio CAPTCHAs. Web site accessibility is a very big issue.

In order to use the captcha you must place a line of HTML code in the form where you would like to verify human submission and you must have a way to receive a confirmation from our servers that the submission is valid. Typically this means that you need to be using a server side programming language such as perl, cold fusion, ASP 3.0, ASP.net, etc. You also need a way to POST to our server.

Answer: Yes. Blogger blogs require a captcha for creating each new blog. Wordpress blogs do not require a captcha.

It's not a common practice, but if the captchas contains the same configuration parameters (same with, height,...) you can add more than one. lt;input type="button" name="hdwnc" value="new image" onclick="document.getElementById('captchaimg').src =document.getElementById('captchaimg').src+'&'+Date();" /> lt;a href="#captchaimg" onclick="document.getElementById('captchaimg').src =document.getElementById('captchaimg').

Your web hosting account must have PHP 4.0 or newer, with GD and Freetype libraries installed and enabled. GD is a library in php that have functions to generate images, and Freetype is needed to display text by True Type fonts. Both libraries are installed by default on most web hosting accounts, and in the rare cases when they are not present they can be easily installed by the admin.

When the Captcha Verification is ON, visitors from these IP Addresses and Domains will be directed to a page where they will have to enter a special code to verify the click is via human interface.

Either the image link in your page is wrong or our server is down. The link to the captcha image on our server is located at: https://www.teleportjobs.com/captcha/captcha_gen.asp?uid=XXX where XXX is your unique webmaster id assigned to you when you registered for our webmaster tools. If you are using classic ASP (ASP 3.0) and copy and paste the link code generated in your captcha management page you should not have this problem.

There is a configuration file containing all settings of the script. You can adjust this configuration file easily with our online tool, that will alow you to customize the captcha image. After getting the desired effect, just save the configuration file to your computer and then upload it to your web server, inside the captcha folder. If you are having any kind of problems installing our Captcha script, please contact us.

Note that the image is not displayed when editing in Dreamweaver. The image is displayed when the page is loaded with a browser. The path to the image (an ASP file) is wrong. Be sure that the paths in your local Dreamweaver matches with relative paths in your online web site lt;input type="button" name="hdwnc" value="new image" onclick="document.getElementById('captchaimg').src =document.getElementById('captchaimg').

When you post the users captcha submission to our server you will read the response from our server. We will post back True, False, OR an empty string. True means that the user entered the correct text that matches the captcha image and you can let the user continue. False means it didn't match and you probably want to tell your visitor that. An empty string might mean that our server is down. See "No image appears when I try to use your captcha. Why?" below.

There are a couple of reasons why this would happen. The first reason is that you are trying to use our captcha for free and you have not followed the guidelines for this. See "Why is it free?" above. The second reason is that you did not validate your email address. When you register as a webmaster to use our free tools we send out an email to the email address that you supply. You must click on the link in the email before logging in and using our free tools.

There are a few reasons why you might see this message. The first reason is that you have called the image prior to registering a domain license. You must register a free or pay for a domain license first. The second reason is that you have registered a domain name that does not match the domain where you are placing the image. When you register a domain it should be formatted like this: www.mydomain.com. It should NOT contain http://, https://, or sub pages.

All current revenue share products require a sign-up with the revenue share program. You do not have to go through the sign-up process, simply enter the captcha (letters/numbers as shown in the image) and click Submit Query. You will only be asked to do this once for each revenue share program (i.e. one time signs up for all Betfred properties). However, you will need to re-install the property after entering the captcha.

Note that the image is not displayed when editing in Dreamweaver. The image is displayed when the page is loaded with a browser. The path to the image (a PHP file) is wrong. Be sure that the paths in your local Dreamweaver matches with relative paths in your online web site The GD 2 Image Library for PHP is not available. Maybe you can contact your web hosting service and request it.

CAPTCHAs are created to differentiate real human users from automated scripts. Some CAPTCHAs can be solved by advanced computer algorithms. A common workaround is the outsourcing of CAPTCHA solving to human agents in developing countries. By using a CAPTCHA web service, we can constantly monitor the quality of the CAPTCHAs we are generating and instantly adapt them if we see they have been hacked.
