Picture backgrounds for slides can work awesome, or just play spoilt sport! The key is to choose a picture that’s not crowded and also select a picture that is less saturated, or with fewer colors. This is important because anything that you place over a picture background on your slide, such as text, charts, or even other pictures need to stand out over the background.
