WordPress Plugin: Nivo Slider Loading Slow

Nivo Slider is one of the best slider tools available for WordPress … until you’ve had too much fun and suddenly have too many images in it. So what do you do when Nivo Slider takes too long to load? Add a single line of CSS, hide any image that doesn’t need to be displayed initially.

.nivoSlider img:not(:first-child) {display:none;}

Now, as you may know the :not and :first-child selectors are CSS3 so anything before IE8 will still see long loading times.
