images

An image says more than 1000 words... in most cases. If you want to support your argumentation on a slide with an image please consider the following tipps:

Use an image to provide additional value to your message. Do not use it to just fill a blank space or because some word on your slide is related to a cool image your found on the internet:

Always reference your sources when adding images.

Do not use cliparts. Most of them look very cheap or old-fashioned. Plus, they often do not provide added value as shown in the following screenshot of a slide that was recently used in one of my lectures:

Do not stretch small images to fit to the slide. They will become very pixelated. Use images with a higher resolution instead (please!!!). This does not only look more professional but also helps the audience to realize what exactly is shown on it.

Do not skew images! Either crop them or if the image is to large than put it on a own slide.

Adjust the background color to your slides background. It does not leave a good impression on the audience when the boarder between a graphic and the normal slide background is clearly visible (see picture above).

Use images as a replacement for your background so that they fill the whole slide (example taken from Garr Reynolds - see advises section):

Example for a redesign/ adjustment of images in slides that combines most of the given tips (from Slideshare):
