IE7 Gets "Red X" when using jQuery Hover

I am using a preview script via http://cssglobe.com/lab/tooltip/03/

The problem is that when I use SRC tag in thi开发者_如何学JAVAs script - I get a big fat red X - in IE7 BEFORE the image is rendered. Once the image appears - all looks ok.

Is there anyway to "hide" this before its loaded or something ? Love an help anyone can provide.

Is the red "X" the placeholder for an image that cannot be found. If so try pre-loading the image or using a sprite so that it does not have to do an HTTP request on the tool tip.
