but you can obviously have an overweight horse and a skinny pig.... but that is rare.

compression ratios are not always the be all and end all. To continue your simile: Jpeg's are sleek - three legged - race horses

what program are you using to edit your PNG files?

I've never actually used PNG's but if I do it will be with Photoshop. The only reason I began this discussion was to get some kind of feel for what everyone else was doing. It's only been within that last few months that I've had anything to do with publishing material on the web. Certainly I've been transfering image data over the net for years, but that was always in Tiff format. Although I'm not unfamiliar with Jpeg's, having used them for web based appraisal/contact sheets, I don't actually like them very much. Jpeg's suffer from appalling losiness even at relatively minimal compression levels. Add to that the total lack of any gamma information and the image as seen by a.n. other on a badly adjusted monitor just leaves me cold and sweating.

yeah I was just curious.. I have never manipulated a png as a png is Photoshop. I always use Fireworks for my png files. Does Photoshop even offer png32 as an option?
I've mentioned in other threads that I started out by using all Macromedia products for web design and reserved Adobe to print material (since the merger though, it is becoming a bit more blended).

I've used png files, as I have to send files in that format, for use on mobile phones, But I do the artwork in psd, then save as png, to send out.
My understanding of png is as a compression suitable for quick download to portable equipment, hence, PNG - Portable Network Graphics.

It was developed as a need to the alternative to the LZW compression patents. Its has a couple of key features, namely lossless data compression, indexed and alpha channels.
It does not support CMYK... this makes it more suitable for the web but not necessarily professional work.
Fireworks png's are a totally different animal. An original fireworks png is a vector based (not bitmap) file that can contain layers and other data... once it it exported as a standard png, it loses that quality.
