Hi Dhruva,
You can try “tinyMCE Advanced” plugin enable the feature “pasting of image source”, it allow you to copy & paste clipboard images (screen-capture) into WP Editor Comments Plus textbox, work great with Firefox, Safari, Chrome.
The image will be saved in database, be careful people may paste a huge image.
Hi Kentaro Fischer,
I’m also seeking for the upload feature, for PDF or document upload purpose.
I have try install “Comment Attachment” but it not compatible with your plugin, nothing will be sent when posting a comment.
