I’ve created an AE composition for a personal project to simulate a slide projector. Just drop in 9 jpegs and follow the Read Me on Text Layer 1 to see how to create your own 30-second simulated slide show. Includes sound effect.
You can download the project here:

4. align starting point of jpeg1 to starting point of text layer 1
5. drag jpeg 2 from project list and drop into timeline above text layer 2
6. align starting point of jpeg2 to starting point of text layer 2
7. repeat with jpegs 3-9 to text layers 3-9
