title: knitr (R) - how not to embed images in the HTML file?
body: <p>This is probably very easy but I can't seem to find it in docs. I would like to not embed the generated images in the HTML file itself.</p>
  
  <p>So basically I want knit2html() to produce a HTML file with seperate image files (which are then linked to / shown in the HTML). The basic behaviour is that the script embeds the images as a base64 string. The problem with this is that in IE, large images won't show up (i.e. appear to be missing). Any idea how I can seperate the images from the HTML output?</p>
  
  <p>My example .Rmd file ('knit.Rmd'):</p>
  
  <pre><code>```{r}
  plot(3)
  ```
  </code></pre>
  
  <p>And my .R file to generate the HTML from this:</p>
  
  <pre><code>library(knitr)
  
  knit2html('knit.Rmd')
  </code></pre>
  
  <p>This example generates a HTML with the plot as an embedded base64 string.</p>
