This is a great time to take advantage of knitr's built-in dynamic customization features for output types. Ths was tested with both output targets...

````{r img-setup, include=FALSE, cache=FALSE}
out.format <- knitr::opts_knit$get("out.format")
img_template <- switch( out.format,
                     word = list("img-params"=list(fig.width=6,
                                                   fig.height=6,
                                                   dpi=150)),
                     {
                       # default
                       list("img-params"=list( dpi=150,
                                               fig.width=6,
                                               fig.height=6,
                                               out.width="504px",
                                               out.height="504px"))
                     } )

knitr::opts_template$set( img_template )
````

If you don't want to use the img_template for every image produced you can either not call the set function and instead add opts.label="img_template" to the params of the chunks you want to use it with, or override the img_template by specifying the params explicitly for the chunk.
