Ok... well thats different.
For everyone confused, instead of "COPY IMAGE LOCATION" and then clicking on a image button and pasting the URL into the popup, or into a <img> tag like on scout, the way to get a full size image is as follows:
1- Find image else where on interwebs
2- Right click and do "COPY IMAGE" not copy image locaion
3- Return to the hide
4- In the body of the new message, where you would be typing the text.... right click and select paste.
5- This pastes the image directly into the composition window.
6- Click POST
