Ive been thinking how to do this kind of a styling in a website ? Search some thing on google then right click on the google logo and click to view the images this is what I got http://www.google.com/images/experiments/nav_logo78.png so for the whole page only that picture is used and by some function needed image is displayed How to do this ? are there any plugin to do this stuff ?
No but using CSS you can do this. It is commonly termed as Image sprite. See a simple example here - Flicker Free Image Button Rollovers
