Answer 1

You can use

```{r, echo=FALSE}
knitr::include_graphics(path,  dpi = NULL)
```

in a chunk and then set image height and width options in the chunk options. This should work with all output formats.

Answer 2

This should work:

<div align="center">
<img src="fig1.jpg" width=800 height=600>
</div>

Simply adjust the width and height as required.
