OK, getting some funny stuff on this year-old solution.

To wit, if I include a table in the page, I get the caption labels.

```
> pandoc -t beamer -o Slides.pdf
---
header-includes: \renewcommand{\caption}[1]{}
title: Title
author: Author
date: March 11, 2022
...

![\ ](image.jpg)
```
works as expected. No caption label below the image.

Now add a little table to the end (or the start), and the label pops back 
up:

```
> pandoc -t beamer -o 
/Users/john_muccigrosso/Documents/Academic/Talks/Perugia/Slides.pdf
---
header-includes: \renewcommand{\caption}[1]{}
title: Title
author: Author
date: March 11, 2022
...

![\ ](image.jpg)

-----

| table |
|:----:|
| cell |
```

This happens to every image in a slideshow.
