Inserting images through TinyMCE

I would like to use TinyMCE to insert images into content area and then position them using css.

The problem I am having is that I am unable to insert an image. The pop up dialogue shows the folder tree but when I click on images folder thumbnails are not loaded.

Is there an option in System Settings where this needs to be turned on?

Any help would be much appreciated!

It’s a bug in 2.1.1: http://modxcms.com/forums/index.php?topic=63523.20

Thanks!

This solved it:

The solution is to edit the "manager/assets/modext/build/widgets/core/modx.rte.browser-min.js".

Find:
Code:

this.view.run({dir:A,ctx:MODx.ctx});

and replace it with:
Code:

this.view.run({dir:A,wctx:MODx.ctx});
