That view is called the photo view and all communities are open to using it they would need to go to their settings. It's important to note that communities can only suggest by default it's still the consumer's choice.
But perhaps you're talking about opening up that view style to all consumers at all time. This is something that is doable BUT it's not a popular view style nor helpful in many cases (mostly just helpful for photography communities) so there is a give and take... do we give all options all the time or do we not overwhelm the majority of users who would hate that viewstyle most of the time? Perhaps there is something in settings that can be done to let users enable that view style however we need to think carefully about how we make sure the settings doesn't get to overwhelming. I'm guessing we will tackle it in the future after we tackle some big things... in the meantime we also would love to figure out if the 3 to 4 view styles really are the best options or if they can be tweaked to be even better. For that we will take mockup suggestions if anyone had any. For sure making sure the most used view styles are best should be top priority.
