The First slide shows the admin page for the plugin a link to which is added on the 'Installed Plugin' page and the main sidebar. On the left pane of the page it shown how to use the shortcode. On the right pane you get to have some important links.
The Second slide shows an example of the shortcode used on my blog to generate the dynamic screenshot of my homepage. The image shows up almost immediately and even if it doesn't the headache is not yours it will automatically refresh the page.
The Third slide shows the raw format of the previous post, in second slide. Simple and easy to understand the shortcode has 5 attributes and the defaults of every boolean is true. One important thing to note is - you must add the http or https protocols to the url.
