The original Wallbase theme is very similar to Shuttershot , the difference is in the location of the sidebar, in this theme it is located on the right side. The template is perfect for a photo site. After activation, a menu with settings and a tab with instructions for using this theme will appear. If you want the block with the latest entries to be displayed on the main page, this is all configured in the theme settings.
In the WP control panel, after activating the theme, the Slides tab will appear, click on the Add New button and add site background slides. You also need to put permissions on the cache folder 777.
