1) Do you mind providing more details on what issues you are having when you load the demo.
Kindly refer to the link below for your guide on how to install the demo
2) Yes, as stated on the link I provided
It should be noted that demo content may not look exactly like our demo websites for numerous reasons. One of the biggest reasons for this is the fact that much of our content is either created by us directly or licensed specifically to us, so it is not available for redistribution (i.e. images, videos, et cetera).
Though there will be placeholder images so you can easily change those with your own.
3) After loading the demo, you will exactly have the same layout minus the images.
