SecureImage

This plugin adds a dynamically generated text key over a set of built in .png backgrounds. A person posting a comment will have to enter the text key from the image before WordPress will save the message. SecureImage requires the ​ImageMagick toolset and access to a font library.

Installation

1. Download secureimage.php from the repository.
2. Upload the file to your wp-content/plugins directory.
3. If ImageMagick's 'convert' isn't in /usr/bin, you will need to update the script with it's current location.
4. In the WordPress Admin Panel, activate the plugin on the Plugins tab.
