When	
  working	
  on	
  the	
  Web,	
  you	
  
want	
  images	
  to	
  load	
  quickly.	
  One	
  
way	
  to	
  do	
  this	
  is	
  to	
  slice	
  the	
  image	
  
into	
  smaller	
  pieces	
  for	
  loading.	
  
	
  
Slices	
  are	
  categorized	
  by	
  type	
  and	
  
should	
  be	
  named	
  the	
  same	
  way:
