Attaching in-line data images, pasting from Word/Clipboard etc

Hi Everyone,

I am relatively new to Foswiki and I am looking for a way to copy images from the clipboard straight into the TinyMCE editor. I came across some other questions that made it seem as though this may be possible via the ImagePlugin. I am, however, unable to figure out how to get it working. For in-line data images does the image already need to be in a DATAURI format or is there someway to set it up so you can easily copy from the clipboard straight into the editor?

Any help would be greatly appreciated. Thanks!
