I would recommend writing the conditional just to give the GIF to IE6. Other IE's will handle PNG's just fine.

Make sure that PNG is the format you want. When it comes to solid colors and type GIFs do fine on all platforms. If you are generating photos then JPGs are usually best as PNG file size becomes a problem. PNGs are great when you need drop shadows with alpha transparencies.

Yes, always go by the individual site for making browser support decisions. However, I have noticed substantial changes in IE6 & even IE7's share on general sites over the last 8 months. Maybe the long anticipated irrelevance of IE6 may not be far off. Can I get an "amen" on that?

Thanks,
