title: Fullpage picture in two column layout
body: <p>I'd like to insert a picture (figure) into a document which is using a two-column layout. However, I want it to take one whole page and not be centered on one of the columns. Currently if I add a <code>[p]</code> modifier to the figure, the whole image lands on the last page, instead in the middle of the document.</p>
  
  <p>How can I force one page to switch back to a single-column layout and insert a single big picture there?</p>
