in-browser WYSIWYG html editor

Hi, I'm setting up a website and one of the needs is a good in-browser WYSIWYG editor. I want to be able that people with no HTML knowledge can manage to edit & format content. I've looked at several utilities, such as the one used in postnuke. I need something with more image manipulation possibilities. eg: list all images on a dir on the server when you click the insert image button. cfdev's activedit (http://www.cfdev.com/activedit/) is such a tool but i find it a bit too expensive... Could anyone help me ? Thx very much Serge
