Apply transparency to a picture
When you position text over an image on the slide, you may want to make the image lighter or transparent so it doesn't interfere with your content. You can adjust the opacity of a picture to make your logo or text pop, adding visual interest to your slide without distracting from your message.
To make the whole picture area transparent,
1. Tap the picture you want to adjust transparency and choose Format option.
This will open the different picture formatting options on the bottom pane.
2. Use the Transparency slider to increase or decrease the picture transparency.
