Precaching HTML image resources
<p>I wrote a <a href="http://cam.dabase.com/" rel="nofollow">web cam viewer</a> where the <a href="http://cam.dabase.com/hgweb.cgi/file/tip/main.js" rel="nofollow">javascript source</a> basically sources the image according to an "active" class in a list.</p>

<p>I was wondering what are good modern techniques to make images load faster in the background, so a user can get a better experience flicking through images.</p>

<p>Obviously it doesn't make sense to download all images, I imagine it needs to be like when one scrolls through a Google map in principle, images are loaded on demand.</p>
