You can insert a background in two ways.
- Backgrounds in the media library
Click on the media library button in the taskbar (second button to the left) and a new window appears. Select the option ‘Backgrounds’ and a menu unfolds. Browse for a background or pick one from the submenu. Click on the background to insert it in your page. The media library closes automatically. - Backgrounds in the page manager
The page manager is located in the bottom-right corner in Presenter. Open the page manager by clicking on the current page number. Select the page on which you wish to insert a background. The page border turns yellow in the page manager. Next, select the three dots in the top-right corner. A menu unfolds. Choose ‘Select background’. The media library is opened. Select a background, the media library closes automatically and the background is displayed on the entire page.
Activate the 'Backgrounds' button and select the colour 'White' to erase a background.
