The ideal cover image of your presentation (the slide that sits on the projector while the audience walks in) would be one that tells your whole story so perfectly that the presentation itself can be skipped. Many people try to reach this level of perfection by putting up a messy collage of different images, a very tricky visual concept or a highly tacky and cliche stock image that represents the values of the brand: young, healthy, lively, dynamic, and social.

I am less ambitious and usually pick an image that fits the corporate colour scheme of the client and is a preview of an image that I use on a very important slide somewhere inside the presentation. It looks nice and calm when the audience enters, and it will generate that instant recall of that important slide when I show it for the 3rd time on the closing slide.
