This can be a helpful jumping off point as you plan your implementation. ## Create a digital photo frame You can display a live photo gallery on a digital photo frame, updating dynamically in real-time. 1. Call [Create Project](https://dev.wix.com/docs/rest/business-solutions/portfolio/projects/create-project.md) to create a project that will act as the photo gallery, allowing you to store and manage photos represented as project items within the gallery. 2. Share the newly created project's ID with those who need to access the gallery so they can add or remove photos from the digital photo frame. 3. Listen for [Project Item Created](https://dev.wix.com/docs/rest/business-solutions/portfolio/project-items/project-item-created.md), [Project Item Updated](https://dev.wix.com/docs/rest/business-solutions/portfolio/project-items/project-item-updated.md), and [Project Item Deleted](https://dev.wix.com/docs/rest/business-solutions/portfolio/project-items/project-item-deleted.md) events to detect when new photos are added, existing photos are updated, or photos are removed from the gallery. 4. Periodically call [List Project Items](https://dev.wix.com/docs/rest/business-solutions/portfolio/project-items/list-project-items.md) to retrieve the latest gallery content and ensure the photo frame reflects real-time changes.
