There are 2 ways to do this:
- Use the Pages feature to create pages on your website and add images to those pages. Pages provide a powerful way to add content to your site. Click on Website Builder, then Pages to manage the pages on your website.
- Use the visibility feature when creating/editing a project to select whether it should be visible on ArtStation.com or only on your website. This is useful if you want to have a portfolio-type experience. This option is only available to users with the Pro Account.
