Sometimes it can be very frustrating building websites that are cross-browser. One of the many issues is transparent png images in IE6.
PNG’s have enabled us to make beautiful images for websites with amazing transparency etc. There is a very simple way to make transparent png images work in all browsers.
This method uses CSS to fix the issue. You can define a class such as ‘transparent’ and apply that to the images whose transparency you want to make work in ie6, or simply use the fix in CSS for the img tag (therefore making all images’ transparency work in ie6).
