This will help you.

The catch here is IOErrorEvent. If images not loading correctly it throws IO_ERROR EVENT (might be incorrect path). Also aware of Cross Domain Security issue.

protected function img_creationCompleteHandler(event:FlexEvent):void
{
    img.addEventListener(IOErrorEvent.IO_ERROR, function(event:IOErrorEvent):void
    {
        img.source = "url";//Make sure it should be Right path;
    });
}

<s:Image id="img" toolTip="Hey tooltip here" creationComplete="img_creationCompleteHandler(event)" />
