Internet Explorer 5.5
PNG transparency with IE 5.5 and IE 6
The transparency issues in IE 6 and lesser are a well-known problem. Tough the older versions are less used it is important to handle this problem if you want to make your website working in all versions.
The problem occurs if you want to show a png-file with alpha transparency in IE 5.5 and 6.
After creating your page, adding the png-image (with alpha transparency) and accessing it with IE 6 or less you will see that the transparency does not work.
If you want to you can use

to render your page on different versions of your browser (for example if you don't have a specific version of the Internet explorer)
The goal is now to find a solution how to make the alpha transparency work for each version of the Internet Explorer.
