How do you get a stockchart chart into a post? I follow the directions in the Agoracom movie, and their directions work with images at other sites, but with stock house charts, what I get is

I have seen StockChart images posted in previous posts, but do not do how to do it. (I right click the stockchart image, and select "Copy Image Location". Then in my post, I select the tree and paste the image URL. The result is seen above)

Can anyone guide me here? Thanks.
