If you want to showcase your works, then you need to install a free plugin called Portfolio Post Type.
Once you’ve successfully downloaded the zip file of the plugin, head to your WordPress Dashboard and select Plugins > Add New > Upload. Add the zipped file in the field there and click Upload.
Upon successful upload, you’ll be prompted to activate the plugin. You’ll then see a new Portfolio tab in your WordPress Dashboard Menu Sidebar.
To display the portfolio section on the Front Page, go to Customize > Front Page Sections: check Portfolio Section. First set the order and visibility of the section in the panel called Visibility & Sorting. Then you can customize the section > Portfolio Section.
Portfolio Item edit
Upload project images to the main content editing field. Enter the description of the portfolio item in the Excerpt field. (of course, you can still enter a work description in the main content field)
You can enter project meta-information (such as date, your role, camera type) by adding Custom Fields. (2)
Valid key names:
date, role, brand, camera, location, client, skills. Please note that key names are case sensitive and must be written in lowercase.
When you created a few portfolio entries, you can set some options for the portfolio via Customizer > Portfolio Options.
