Hm, that is not the goal to me. It could be: * Entertain them. Meme pics should work great here. * Inform them. Here I would suggest to not use slides at all but rather show a document (blog post, handout, etc) which works on its own afterwards. This is also my ideal approach for these meeting presentations where everybody asks for the slides afterwards. * Persuade them with a clear call to action. Here meme pics are also better in my opinion. However, I'm quite liberal here. The "pic" could be a complex diagram. My point is make a clear single (!) statement with the slide.
