transparent png not working in IE 6
I created a png logo with a transparent background to use on my company's website. It looks great in Firefox, but in IE6 it shows up with a light grey box around it.
This is my first attempt at using a transparent background for a web graphic, so I have no idea why this is happening. Did I probably do something wrong in creating my png image, or does IE6 not support transparent backgrounds on these files? If anyone knows the answer, please let me know.
Thanks in advance to anyone who can help.
