issues with copy/paste within the same document

[oferlaor]

ugraded to 2.0.9 and I still have two issues:

I created a new document and added a screenshot to it. Then copied it over and over with some sample text. The following two issues occured:

1. Once in a while, I get an error that I described previously (you can see in the screenshot).
2. When I copy or cut/paste - it re-uploads the images each time, so I get a lot of duplicated images.

It should check if the image is already uploaded or originates from the current site (in which case, it shouldn't be re-uploaded).

I think we need a google docs button that should turn on/off the HTML behavior and also be able to control the default state of this button.

@mcguffin thanks!
