When selecting an image in ImageEditor only the image placeholder shows

I’m using 0.9.6 for the first time.
The issue I am having is in the path: /manager/media/ImageEditor/editorFrame.php.
The image src was given as a relative path and so the browser looks for e.g.
http://mydomain/manager/media/ImageEditor/assets/images/logo.png
instead of
http://mydomain/assets/images/logo.png

In the Administration console, Tools -> Configuration -> Interface & Features -> the ’Resource URL’ has not a leading slash, e.g. ’assets/’ as is suggested in some form posts. In the case when the ’Resource URL is set: ’/assets/’ then not only the Image editor is not working but also the Tiny Mce finds only the image placeholder .

Please, help me to fix this problem.

Thanks

Please, is there someone who had the same problem or knows the solution?
Thanks

it does seem that mod-x does not set this directory up correctly on default install. I’ve just fixed this problem by setting the resource URL config to an absolute path. e.g for standard install /modx-0961p2/assets/
