image problem .png issue

There is supposed to be a problem with .png images when using Internet Explorere 6 and earlier versions.? ? The problem has to do with transparency issues that make the image look? choppy. ? There is some kind of code snippet resolution to this problem. I am looking for someone to place the code in my [login to view URL] page and provide the supporting files and instructions so I can upload back to my site.? This should be a very simple problem for someone who has done this before.
