title: Including texture files into the collada file
body: <p>I want to include my texture image files into my collada file. 
  Now I have many files: the .dae itself and the .png texture files. </p>
  
  <p>However I want only one file: the .dae, but with the textures included into it. </p>
  
  <p>Could I somehow store the .png images in the .dae file itself?
  Is it possible?
  Thank you in advance!</p>
