Already in the past, I mentionned this stupid issue with IE… if you don’t use GIF image, you have no transparency ! The full support of PNG image is not supported by IE. To refresh your memories : usage of gif instead of png.
I was surfing and I found this hack. Which is more than easy to implement and it seems it works more than perfectly !
It is composed by a single clever java script ! Amazing ! Microsoft developpers should have a look at the code ! 🙂
