This article, part 5 of a series on image optimization, talks about the use of transparent PNGs with IE6 and why the AlphaImageLoader hack is bad and a very interesting solution
This installment of the image optimization series is about the IE-proprietary AlphaImageLoader CSS filter, which developers often use as a workaround to solve transparency issues with truecolor PNGs in IE. The problem with AlphaImageLoader is that it hurts page performance and, therefore, hurts user experience. I argue that AlphaImageLoader should be avoided when at all possible.

YUI 2.6.0 introduces a new Carousel Control, offers the Paginator Control for general use (it was previously bundled with DataTable), includes more than 450 total fixes, enhancements and optimizations, graduates eight components out of “beta,” and now ships with more than 290 functional examples.
The YUI library has grown to include two new components:
