Install filebrowser plugin

Hello,

Since several hours I try to install the 'filebrowser' plugin.

I read the documentation and I did this :

I put the two following plugins like this : (le 'filebrowser' pluging depends on the 'popup' plugin)

-- ckeditor (repertory)

------ config.js

------ plugings (repertory)

---------- popup (repertory)

-------------- plugin.js

---------- filebrowser (repertory)

-------------- plugin.js

And then, the config.js is edited like this :

CKEDITOR.editorConfig = function( config ) {
    config.extraPlugins = 'popup';
    config.extraPlugins = 'filebrowser';
};

When I run the web page, the editor is displayed but when I want add an image, the filebrowser button/tab doesn't show in the image selection frame.

What have I forgot ?

Thanks to your help.

Bye, ;)
