An image sprite is a collection of images put into a single image.<\/p>\n

What is advantage of using image sprite? <\/strong><\/p>\n

    \n
  1. Reduce multiple server requests.<\/li>\n
  2. Sprites reduce the number of server requests and save bandwidth.<\/li>\n
  3. Another advantage of sprites is that you can keep all your images in one location and in some cases it makes more sense (for menus and so on).<\/li>\n<\/ol>\n

    A real life Example <\/strong>
    \nIf you use sprites for a “mouse over” display, the user won\u2019t experience image disappear for a second… and it looks really good when you have heavy graphics in your site.
    \nIf you change the image instead of just moving the sprite around it will load a new image and the loading time can be visible to the end user.<\/p>\n
