title: Plotting several images in the same plot
body: <p>I'm trying to plot small images on a larger plot... Actually its isomap algorithm, I got many points, now each point correspond to some image, I know which image is it... The porblem is how to load that image and plot on the graph? 
  One more thing I have to plot both image and the points, so, basically the images will overlap the points.
  Certainly, the type of image given <a href="http://web.mit.edu/cocosci/isomap/handfig.html" rel="nofollow">here</a></p>
