Hi,
I noticed today that despite unchecking various image-related options in the TinyMCE editor input settings, I wasn't able to prevent CMS users from inserting images into the rich text box. The insert -> image tool still remains visible and functional.
Here's what I've tried so far:
- 
Unchecked the ImgUpload feature. 
- 
Unchecked the following plugins: pwimage, image 
- 
Removed pwimage tool from the toolbar. 
Is there another setting I need to disable to completely remove image insertion? I couldn't see anything.
