Description: Preload an image, load the image into the Web browsers memory or cache if applicable. Returns true or false if the image is completely loaded, returns true if the image was not able to load. Returns undefined if the function’s argument is not valid.

Note: Web browsers only open one connection per file requested, this means that if you run this function for the same image file more than once, the image will not load more than once, because of this we can check if the file has been completely loaded.

Method:

imagePreload ( src_s );

Example Usage:

imagePreload ( “img/myimg.jpg” );

Loads the image into memory

Example Usage 2:

var file_s = “img/myimg.jpg”;

ImagePreload ( file_s );

var intv = self.setInterval ( function () {
if ( ImagePreload ( file_s ) ) {
// do something
clearInterval ( intv );
}
}, 500 );

Load the image into memory, check if the image is completely loaded and wait till the image has completely loaded.
