Image Captcha differs from most, in that it requires visitors to select one of a series of images that differs from the others.  There is nothing to type, so you don't have to lay the mouse down to enter impossibly obscured words.  It's quick and efficient and most users will actually enjoy the exercise. '''Those already logged into the website as registered users will not be presented with the Captcha''', but will be given direct access to the protected page.

The Image Captcha display consists of a series of 'fill' images which are all the same. A different 'target' image will be arbitrarily positioned among them.  You can choose to employ one or more sets of images included with the mod, or you can use your own custom images.

Prior to TNGv11 the Image Captcha Mod replaces your current TNG_captcha.php file, if any. It removes it altogether when uninstalled. Not to worry, TNG works fine without it, but if yours contains code you want to keep, please rename it so you can return to it later if you need to.

Beginning with TNGv12 Image Captcha modifies the TNG-supplied captcha file and returns it to factory spec upon removal.

Image Captcha provides language support via text files (cap_text.php) '''in the mod's support folder''', under languages. There is no need to copy them to the TNG language folders because Image Captcha Mod uses them "in place" to prevent corruption of UTF-8 files. Other languages can be added by using these files as templates.

<b>ImCap version 12.0.0.5</b> only works with TNGv12. Vintage images in this mod are new and come from attractive 19th and early 20th century stock in the public domain.  They are slightly larger than in previous versions, but you can set the display size up to 90 px square. If you want to retain your current image set, you can do so by identifying them as custom images in the mod's edit screen and setting the size between 60-90 pixels.

NOTE: <span style='color:#990000'>If you've upgraded your version of Image Captcha and are not seeing the images, you've probably neglected to uninstall the older version first.  Check your customconfig.php and make sure the old version number is not listed after the new one.  If so, just delete the old version number from the file.</span>
