Hello, I would like some help to integrate and ckfinder ckeditor in my application. the application is built on .net and what is the ckeditor works perfectly.

I have copied following a manual ckfinder(aspx version) folder in the project, and add this code.

 CKEDITOR.replace ('editor1'
 (
 filebrowserBrowseUrl '/ ckfinder / ckfinder.html'
 filebrowserImageBrowseUrl '/ ckfinder / ckfinder.html? type = Images'
 filebrowserFlashBrowseUrl '/ ckfinder / ckfinder.html? type = Flash',
 filebrowserUploadUrl '/ ckfinder / core / connector / aspx / connector.aspx? command = QuickUpload & type = Files'
 filebrowserImageUploadUrl '/ ckfinder / core / connector / aspx / connector.aspx? command = QuickUpload & type = Images'
 filebrowserFlashUploadUrl '/ ckfinder / core / connector / aspx / connector.aspx? command = QuickUpload & type = Flash'
 )
 );

but can not get any image on my local hard drive up to the server. my server is IIS6. I must add something more?
