A designer just gave me the HTML/JS/CSS for a new site design. The page is using the good old fashioned MM_crap methods to preload images.
Should we still be preloading mouseover images in today's world? It feels so 1998.

5Ideally you should be using [sprites](http://css-tricks.com/css-sprites/). – Marcel May 29 '11 at 07:23

True - That might be less work too. – Jeff Handley May 29 '11 at 07:30

Yes, absolutely. Even on fast connections, DNS lookups or connection hiccups can create a notable delay when loading an image. You don't want that on a mouseover.
No need to use Dreamweaver's preload code though: See What is the best way to preload multiple images in JavaScript? for alternatives.
Plus, there is a very interesting alternative of course (as mentioned by @hd and @Marcel): CSS sprites. Depending on your situation, they can be a superior solution - if you're working on something new, it may well be worth the switch.

@hd see [What can I do when getting "Sorry, we are no longer accepting questions from this account"?](http://meta.stackexchange.com/q/86997) for some help on that. – Pekka May 29 '11 at 07:25

1Marking this as the answer since it answered the question at hand, even though I'm actually going to use CSS sprites instead of rollover images as @hd suggested. – Jeff Handley May 29 '11 at 07:35
