Setting image upload folder via ASP

I have FCKEditor installed as a root-level folder within my IIS configuration. I can access FCKEditor from any of the websites/folders in my IIS configuration via an include file. This works great.

I want to be able to set the folder for image upload and file management within an ASP file outside of the FCKEditor folder. So far, I have only been able to set this folder using the 'LinkBrowserURL' and 'ImageBrowserURL' within the fckconfig.js file within the FCKEditor folder. This is a problem in that I need to set a different folder for each website that makes use of FCKEditor.

In my ASP file, I'm using the following code to instantiate FCKEditor:

<!--#INCLUDE VIRTUAL="/fckeditor/fckeditor.asp"-->
Dim oFCKeditor
Set oFCKeditor = New FCKeditor
oFCKeditor.BasePath = "/fckeditor/"
oFCKeditor.Create "sContent"

Is there a property I can access to set the 'LinkBrowserURL' and 'ImageBrowserURL'?

Is there a different method I can use to set these values via ASP?

Thanks for your help.
