Image upload

Hi

From the readme file :

Uploading images and files
--------------------------

There are three ways of uploading files: By using commercial file browser like CKFinder (http://ckfinder.com), by using modules like IMCE, WebFM, Image Browser or by using the core upload module.

To select preferred file browser, under "Administer > Site configuration > CKEditor", adjust
CKEditor profiles. In each profile you can choose which file browser will be used (in "File browser settings" section).
Note: to choose IMCE, WebFM or Image Browser you should install an appropriate Drupal module first.

I have enabled the core Upload module, but still only see CKFinder as an option under my file browser settings. Am I missing something ?

Thanks for any assistance.
