Hello Lukmcd,
You want to make the other pages same as home page? If so, you can’t make the same as home page to other pages. If you want to make the photo gallery on other pages, you have to find the plugin or use Gallery of WordPress. Or, you can customize the theme as your need too. We recommend you to find the suitable plugin for gallery and make the other pages too.
Note: Child Theme is recommended to customize theme.
Regards,
