   Sprites and animations
  Hi all,This should be a simple one :)I have been looking into sprites for a small application that Im making, its not a game, but its visually slick and needs nice PNG based animations to really give it a kick.So, I started researching around on how sprites are implemented to give the highest performance and results, and I keep seeing Sprites with bright pink backgrounds (that Im assuming is converted into transparency somehow?) and they are all in one image, not in many many different files like so:http://sdb.drshnaps.com/objects/19/1780/Sprite/CVS2_Akuma.PNGSo are Sprites typically implemented as one long image with a "viewport and offsets" style approach, or are the sprites on the net just combined for easy viewing?Cheers,Mark
