CKeditor + Media: insert image tag rather than link to image
Insert Module will do that, it will place the image in body field. Support for all major WYSIWYG editors, including tinyMCE, CKeditor.


  Insert is a utility that makes inserting images and links to files
  into text areas or WYSIWYGs much easier. It adds a simple
  JavaScript-based button to FileField and ImageField widgets. When used
  with ImageField and ImageCache, images may be inserted into text areas
  with a specific ImageCache preset.
