Chances are you have seen, heard of or used a captcha code at some point. These codes are simply either a combination of numbers and letters or a math equation that must be entered before access is gained into a site or before a form is submitted. The purpose of the captcha is to prevent malicious use of the website, forum, blog or form. The reasoning is that a human can easily answer a captcha code, but an automated system such as a bot cannot.
When you are creating a website, you will likely find at least one place that you want a captcha form to be included. This is because you want to ensure that only the right people have access to that portion of your site. This is true regardless of whether you are creating a full website, a message board or simply a blog that others can comment on. This means you will want the ability to easily create a captcha form that is customized to match your page and be user friendly as well.
When you download captcha designer software you are giving yourself the ability to do just that. You can create captcha php codes and design them to fit into any website you may want them on. This is done by customizing everything from the background to the font on your captcha site. This makes the captcha less intrusive and allows you to design one that customers do not find frustrating and hard to use.
When you opt for a captcha code on your page you are simply ensuring safety for your website and any potential members you have. The captcha prevents misuse of your site and eliminates much of the spam you would ordinarily get. By using a captcha form you are taking one step towards stopping the wrong people from taking advantage of your page.
You will have the ability to choose a background from available files, templates or standard colors. This small customization of your captcha form allows it to blend in with whatever background you have on your page. Many captcha programs do not allow that alteration and this leaves you with a code that stands out when it shows up.
There is also the ability to alter the size of your captcha php form so that it is as large or as small as you would like. You can decide on the size based on the space you have available and how large you think your visitors would prefer it to be.
Your captcha code itself is also customizable. There are two ways you can choose to have the code presented. There is the option of a standard code which combines numbers and letters for the user to copy. There is also a math equation which must be computed in order to gain entry. The choice is completely yours and you can even customize that captcha code with the length you want and the font you desire.
