@thc2603, Duncan will explain more on this but for now what you have pointed out is a glitch which Duncan and his Team are working on. Just aside note, there are a lot of user stats. out there that indicate there is no advantage (in fact the opposite) of having more than two image slides in the hero area of a website’s homepage… it is how us humans are wired up when it comes to moving objects (checking out for danger) and our reptilian brain.
In general the problem is the stretching of an image to the full width of the browser, but it’s not really clear from the screenshots. Please send the project file to feedback@sparkleapp.com and we’ll take a look.
