The Security Image Addon gives you a great deal of flexibility with respect to how you want the image itself to be displayed on your site.

You now have a choice of security images that can be used on your website. You can use the built in security image feature that is configured on this page of the admin tool. You can also choose to use the security image feature through the recaptcha.com website. To start using their image you will need to of course make the choice in this admin tool here. You will also then need to sign up for the service through the recaptcha.com website. Once signed up you will need to fill in the fields necessary within this admin tool with the api key and private key provided by their website.

This setting allows you to display the security image at the bottom of the Registration Page.

This setting allows you to display the security image on the software's Login Page. Note that if your software edition displays a login box on the front page, that is actually a separate html form than the Login Page. You can apply the security image to your own forms by using the appropriate tag (shown in 'NOTE' below).

This setting allows you to display the security image on the Contact Seller and Tell-a-Friend forms accessible from the Listing Display Page.

<tip c n> The security image can also be used within custom login forms that you may have applied to your site. If so, then simply insert the following tag within the <form> tags of your form where you want that to appear:

{addon author='geo_addons' addon='security_image' tag='secure_image'}

Just make sure you only have one security image appearing on any one page at any one time. If there are more than on security image on any one page at a time the two will conflict with each other and only the second appearance of the security image in that page will have the proper effects.
