I have done some Googling over the weekend and finally I have fixed the PNG transparency issue. Many thanks to Ellen from TheDesignspace. The solution she has provided works well in all major browsers! I knew it that I needed to add a conditional js code and Alpha transparency to make it work in IE6 but somehow it was not rendering correctly in all browsers. I have seen a few tutorial on this topic on different website, and this is the one to actually explain it well.
Again, thanks for sharing…
