title: Using custom map image tiles in LeafletJS?
body: <p>Do my tiles need to adhere to any particular specs?</p>
  
  <p>I have a large image file which I'd like to turn into a map with LeafletJS. I am going to be using the Python Imaging Library to cut it up into all the various tiles I need. </p>
  
  <p>However, I can't find any information about using custom maps in Leaflet. Do I provide Leaflet with the range of X,Y,Z info somehow? Do I give it the pixel size of each tile? Does it figure this out on its own?</p>
  
  <p>To put my question into one concise question: What do I need to do in order to have image files that can double as map tiles with LeafletJS, and what, if anything, do I need to do in my front-end script? (beyond the obvious specifying of my custom URL)</p>
