Images not displaying in Drupal posts.

Hello,

I've been testing out Drupal, to see if I want to use it to rebuild an old Joomla site I maintain.

I've got CKEditor and CKFinder working for content editing and image uploads.  They work great.  When I am editing the post, the image appears, I can move it around, etc. 

The problem comes in when I view or preview the post.  Images do not appear.  The IMG tage is absent in the HTML source that is displayed, for example, on the home page.  Yet if I go back and edit the content item, the image is still there, just as I placed it.

Any ideas about where to look?  Searches in Google and the Drupal Forums are too full of discussions about image modules, etc.  I can't find an answer.

Thanks in advance,
-Jason
