How to import local image using knitr for markdown

Question

I have an externally created png image in a local directory that I'd like to import to a report using knitr. The ultimate target filetype is html. I have no trouble getting my own figures to appear when I create them with R code, but I'm at a loss what I would have thought was a simpler problem.

While I'm at it, how would I import a figure for which I have a url?

If you already have a local image, you can just use the HTML or markdown syntax to include it in your document. HTML syntax is <img src="path/to/your/image" /> and markdown is ![title](path/to/your/image).
