Hi I followed the mysettings instructions to customized the openwysiwys 1.4.7 wanted to change image directories
I aded the topline to setting.js
var mysettings = new WYSIWYG.Settings();
then aded below it :
mysettings.ImagesDir = "myfolder/images/";

then attched it to editor :
WYSIWYG.attach('all', mysettings);

and resolts nothing image files still remain in origenal location on
wysiwyg.js

it seems that the my new sttings function dose not work ??
