Customization of CKEditor

[yxcvbnm]

1. is it possible to have an update safe and less 'complicated' solution for the customization of ckeditor?

2. if someone uses get simple in a subdirectory of root, ckeditor does not show the images. after editing of admin/template/js/ckeditor/config.js as follows, it worked. the solution is not update safe and complicated solution. in the settings, the website url is defined and that would be the baseHref, ckeditor needs.

Code:

CKEDITOR.editorConfig = function( config )
{
    // Define changes to default configuration here. For example:
    // config.language = 'fr';
    // config.uiColor = '#AADC6E';
    config.baseHref = 'http://www.example.com/path/to/getsimple/';
};
