Summary:
I was recently tracking down a bug with JavaScript onMouseOut/onMouseOver handlers in my ASP.NET User Controls. In order to rule out one possible problem – images that haven't been downloaded yet – I decided it would be useful to implement image preloading for my ASP.NET ImageButton controls. I've seen the slick way that Macromedia Dreamweaver inserts the MM_preloadImages() function in its authored pages. So, I thought... there must be a way in my ASP.NET pages to do the same thing. After a little bit of research, I found that there was a way, and it was pretty easy to implement.
