CKFinder is a plugin-based application and as such it can be extended relatively easily.
Enabling JavaScript Plugins
To add a plugin to CKFinder, upload it to the plugins folder and enable it by using the extraPlugins configuration option in the config.js file:
CKFinder.customConfig = function( config )
{
config.extraPlugins = 'dummy';
};
Enabling ASP.NET Plugins
To add a plugin to CKFinder, upload it to the plugins folder and add an include statement in the ASP configuration file (config.asp):
<!-- #INCLUDE file="plugins/imageresize/plugin.asp" -->
