Of course IE6 supports PNG - it just doesn't support alpha transparency, which was fixed in IE7. And by the way, when dealing with PNG-format you might want to read this article:http://hsivonen.iki.fi/png-gamma/"There is no way of making PNG images that match CSS colors in all PNG-supporting browsers. This reduces the usefulness of the otherwise excellent image format. If the image colors and the colors defined in a style sheet need to match, it is safer to use GIF or JPEG."That's what I consider the real problem with PNG, even if it only affects some (oldish) browsers. “PNG files [...] are not willingly supported by Internet Explorer 6, but I believe 7 does support it.”
