so…you open two tabs in your browser. in one, you start a new story. choose a title, and add a picture.
in the other, open up one of your old stories. copy the address in the browser bar at the top of the page (just highlight the whole address, and press Ctrl C , or right click on the highlighted address and click copy on the menu that drops down)
go back to the first tab, the one with your new story, click your mouse into the body of your story and press Ctrl V (or right click and click paste on the menu that drops down).
hit enter twice.
go back to the second tab, pull up another one of your stories, and do the same thing again. rinse, and repeat.
