FCK editor - How to define userfilepath

Hi everyone,

I have this urgent issue here. I don't seems to be able to define the userfilepath correctly. I'm using fckeditor v2.2 on .net3.5

Here is whats happening -

1. My main site (where all the uploading via fckeditor takes place).
> 'http://123.123.123.123/Admin/default.aspx'

2. The site which display all the images uploaded from (1).
> 'http://123.123.123.123/Display/default.aspx'

3. So the userfilepath(virtual path) define was ResolveUrl(~/Content/images/ID), which will give me '/Display/Content/images/ID'.

4. But currently, we moved the site (2) to
> 'http://456.456.456.456/default.aspx'

How am I supposed to defined the userfilepath in this case?
Hope i didn't confuse anyone here.

Your help is greatly appreciated! Thanks.
