Before you do anything tell us what camera you will be using. Some cameras will automatically unwind all of the film and respool the film as you shoot it. This kind of camera will not work fro clip tests. Some cameras will read the canister and not allow you to overide the iso setting. These cameras will not work for film speed testing.
Matt using Firefox I found one of your images, right clicked on the image and chose "View Image." This displayed the image all by its self in the browser window. I copied the url for the image and then pasted the url in the dialog box that poped up when I chose the picture icon in the 'Post Reply' page.
Does this make sense?
