Question No: 35    ( Marks: 5 )

 What are the important properties, methods and event handlers of image object?

1. An instance of the Image object is created using the new keyword

2. The src property of this instance is set equal to the filename of the image to be preloaded

dieImg = new Array( 7 ) ;

for( k = 1; k < 7; k = k + 1 ) { //Preload images

dieImg[ k ] = new Image( ) ;

dieImg[ k ].src = "die" + k + ".gif" ;

Example 2:-

dieImg = new Array( 7 ) ;

for( k = 1; k < 7; k = k + 1 ) { // Preload images

dieImg[ k ] = new Image( ) ;

dieImg[ k ].src = "die" + k + ".gif" ;
