You can change the background of the Digital Album from the Event Settings on the dashboard. Access the dashboard using the following link: https://app.kululu.me/dashboard
In the Event Settings, navigate to the "Appearance" section and then select "Album Background". You have the option to pick a single static background or a collection of images displayed with a slight opacity as the background. You can choose from the recommended backgrounds or upload your own.
If you don't choose an album background, it will automatically cycle through the photos already uploaded in the album by you and your guests.
