I need a specific implementation of a photo gallery album

Hi, I'm getting into the web dev business and I'm building my first wordpress cms website. My experience with wordpress is just one blog: http://www.freshvision.com.ng/, I'm stock because my client has requested a multimedia page for which should be a replica of what is found at https://www.globalfundforchildren.org/multimedia/, the good news is that this website was also developed with wordpress. Pls can you help with a page template design for this.. Thanks
