Hi Gina, the background image is set in "Canvas Properties." There you can also configure whether you want your canvas to be autofit or freeform. I recommend optimizing your background image to 1920px wide.

I found where the background image is. If you right click the "Home" canvas tab and select "Canvas Properties", you will see that there is a background image source "Back 2560px.jpg".

Now what I am curious about is how this background image was created. It looks to me that it was made with html. Is that correct?
