is there any way to one click upload images with a CKeditor? Found this https://drupal.org/project/ocupload but sadly - its for 7.x version of Drupal :(
Have you tried IMCE it can be attached with a number of WYSIWYG editors like FCK Editor, CK Editor, Tiny MCE
Can you upgrade to ckeditor-6.x-1.5. There you can use plugins for the CKeditor. One of the plugins is the IMCE button. This allowes you to skip the image dialog and upload a file. It still isn't a one click upload, but it's better than the normal IMCE upload.
Add the following line to your ckeditor.config.js ['Link','Image','IMCE'],
for the toolbar you are using.
