If you want to do it differently than the tutorial, you can get the url of the picture by having the full size picture open, this seems to be where you are getting
your address. You do a ctrl c (copy) of the address from the command line of that page. In the post a reply box (where I am typing right now)
There is a box labeled "Img" click on it and it will insert the image tags with your cursor in the middle. Simply hit ctrl p (paste) and it will put the url in the right place
with the proper tags. You can see if all is well by using the preview button below. I always preview my posts, so make sure everything works like I wanted and to make
sure I said what I thought I said.
