I do not understand your question so I'll provide two answers:

1. The Universe teachpack supports an optional descriptive clause for  
world programs that allows you to record all events and create a  
series of PNG files from all interactions. It also creates an animated  
gif file. See

  http://docs.plt-scheme.org/teachpack/2htdpuniverse.html#(form._((lib._2htdp/ 
universe..ss)._record~3f))

2. If you wish to use existing PNG files with a world program, you  
have two options:

   -- copy and paste the image from some other application (e.g., web  
browser)
   -- use the Insert | Image ... functionality from the drscheme menus

In the future we will support programmatic inclusion of images from  
files.
