Does anyone knows of a
simple OpenSource Web FileManager with good WYSIWYG that actually works on a simple Hosting Linux account..?

I have tried eznetedit BUT its WYSIWYG html control screws up any path on the Webpage that doesn't begin with a "/" or with the whole URL...
So no image nor link will work or show

I have tried phpxplorer which seems a very COOL script.., if I just could make it work.
I don't even know if is installable on a simple Hosting Account(maybe is a Server level script)

So..., any ideas?
Needs to be OpenSource first, then it could be with a fee if there's no other way.

Thank you very much
