You are absolutely right about text slides. PowerPoint slides are about graphics.

Typical Powerpoint:
Here's what I'm going to tell you
Here's what I'm telling you
Here's what I just told you
Any questions?

It should be:
Here is a photo or video that illustrates what I am telling you.
Now that I'm done, here's a handout you can refer to later to remind you of the content of my presentation.

Absolutely right. And here's a good way to amend your suggested format to make it even more interesting . . .

A real winner of a presentation would include:
1. Here's a question I have FOR YOU about the topic at hand (get the audience interested).
2. Here is a photo or video that illustrates what I am telling you.
3. Here are some more questions I have FOR YOU about what I'm telling you (make sure this leads the audience through a series of points as you make them visually).
4. Now that I'm done, here's a handout you can refer to later to remind you of the content of my presentation.
