Haiku Deck's minimal format encourages concise, bold headlines.
You can import your own photos (http://blog.haikudeck.com/import-images-like-a-pro/) or use the integrated Creative Commons image search for a more metaphorical approach (More about that here: http://blog.haikudeck.com/free-photos-for-all-how-haiku-deck-puts-creative-commons-images-at-your-fingertips/).
Of course, you can include as many steps as you need.
To illustrate the process with your own photos, you can import images from your Camera Roll or computer, or from Google Drive, Dropbox, Flickr, Instagram, or other sites. More details here: http://blog.haikudeck.com/import-images-like-a-pro/
