I placed the following code in the window.onload method. It works but only
on inline images. It will not work if the image is loaded through css. For
the transparent PNG's I use Fireworks 8 and export as PNG 32.
Also, I did not write this code. I got it off of some website. I forget
which and I will link to it if I can find it.
