Microsoft PowerPoint allows you to make one color in a .jpg file transparent. This is useful when you want to remove solid color backgrounds from logos or other graphics.
To set transparent color:

1. From the Picture Tools Section, click the Format Tab.
2. In the Adjust group click the drop down under Color.
3. Select Set Transparent Color.
4. Move the wand to the color you want to make transparent and click.
5. The color selected will be completely removed from the image.
