Clean, easy, effective. You don’t need no stinking JavaScript to preload your images. Nope. Try some tasty CSS and (X)HTML instead! Here’s how.. (only two steps!)
Step 1 — Place this in your CSS file:
div#preloaded-images {
position: absolute;
overflow: hidden;
left: -9999px;
top: -9999px;
height: 1px;
width: 1px;
}Step 2 — Place this at the bottom of your (X)HTML document:
<div id="preloaded-images">
<img src="http://perishablepress.com/image-01.png" width="1" height="1" alt="" />
<img src="http://perishablepress.com/image-02.png" width="1" height="1" alt="" />
<img src="http://perishablepress.com/image-03.png" width="1" height="1" alt="" />
</div>..and that’s a wrap! All images are preloaded and ready for calling as you please. Completely valid, standards-compliant image preloading via CSS and (X)HTML!!

@Caderial: I think we get what you’re saying, but you know that method is not going to work. The way your code is written, only the last instance of the
background-imageproperty is going to be rendered by the browser. That’s just the way CSS works — in cascading fashion.There is a way to do what you’re thinking with CSS3, as I explain here:

@David Bowman – What contribution did your “wise” words bring to this post? In a related topic you authoritatively attempt to suggest that “triad” (underground society) is a better word than “triage” (which is also an uninspired choice in the context, but that’s an entirely different matter). I’m sorry, but you lose any sort of remaining credibility and pretty much anything you say is mere uninformed opinion. Go and educate yourself before you start another tirade.

Jeff,
When a visitor is that rude (yes, I’m talking about David Bowman) there is no need for you to remain polite. You will not lose or offend visitors.
Tell him to buzz off, and to better himself with something more worthy of his stature. Speak your mind and tell the prick to beat it.

Hi Jeff,
Congratulations on solid article write ups. Very good information available here.
Also wanted to ask you if you have considered installing a WordPress Plugin for pagination. Currently the comments span over a huge vertical length. Although you have the scroll to top button installed, IMO, pagination will help a lot. Just my 2 cents to make your blog even better…
