Vartb_pathToImage= "Images/loadingAnimation.gif"

ImgLoader=newImage (); / / image object

ImgLoader.src=tb_pathToImage

Add Img to $("body") .append (""); / / page

$('# Image_load'). Show (); / / showloader

$("body") .append (""); / / add a mask layer

3. Add the corresponding CSS code:

.pageover _ bg {

Background-color:#000

Filter:alpha (opacity=75)

-moz-opacity:0.75

Opacity:0.75

}
