Slides don’t (necessarily) need text

A picture is worth a thousand words; a cliché, but a true one. Let go of the idea that every slide needs text or even a headline, at least in the context of a verbal presentation.
A powerful visual like a picture or an illustration can be even more effective without explanatory text. Break the template and use visuals to set a mood or tell a visual story. Allow the visuals to speak for themselves.
