"Loading Image"-Image

You could use the CSS feature to put a "placeholder" image as the
background, and then when it loads the real image it will be on the top
of it so to speak.

the CSS Code looks something like this

.imagebox{
    background-image: url ("somestockimage.jpg");
    background-repeat: no-repeat;
    width: 100px;
    height: 100px;}

Hope that helps,
