The Power Pics series from Slide Topics is a large collection of images for you to use in your documents, presentations, and commercial work. Each presentation gives you a single theme with 25 carefully-chosen images which you can then download to use in your work.
You can use them to enhance the look of a slide, to create a mood, for a touch of drama, emotion, or wonder, to illustrate a topic, or as an effective background. If the license allows, you can use them to create new images and slides of your own. Of course, you can also just sit back, browse through them, and enjoy them as they are.
Where presentations are concerned, a picture is always worth a thousand words.
