title: Is it possible to stack multiple bitmap images on top of each other?
body: <p>I am not a coder so I was just wondering.</p>
  
  <p>EXAMPLE
  Each image will contain a puzzle piece, and has a blank/see through background (allowing a layering effect).</p>
  
  <p>The user goes through a process to build the puzzle, with the ability to choose different pieces.</p>
  
  <p>The bitmap image is called when the user selects a new puzzle piece and a string is created. Each letter in the string calls a bitmap image and the whole string itself create the users puzzle.</p>
  
  <p>Has this been done before? What can be used to build this? </p>
  
  <p>EDIT:
  I'm wondering if, for a site of thousands of images where each image is called, that this method would save a few kb per image and speed up a website</p>
