How to enable drag and drop picture upload into CKEditor?
Most drag&amp;drop upload solutions are meant for image / file upload fields, but there is one more that integrates with CKEditor: the media module. According to its project page:


  Features: […] Drag and drop upload (requires the Plupload module).


Choose the 7.x-2.x branch, it reportedly has better drag&amp;drop image upload capabilities. Integration of media with CKEditor happens via the wysiwyg module, so if you deploy CKEditor instead via the ckeditor or editor modules, it may not work even if overriding dependencies, because these integrations have slightly differing APIs to talk to CKEditor.
