Hello

Wondered when you open a png in Photoshop CS 1, and alter it then save it, does the png file get re-compressed further, each time you change and save it or does it remain the same?

Thanks

that is because you are not supposed to edit origional work.

open it > select all > copy > file new > paste

then work on it, and it will retain the new settings

24-bit PNGs can be lossless. Most times they are. 8-bit PNGs only contain 256 colors, so it's like editing a GIF file. You usually can resave PNGs and alter them to your heart's content and it won't degrade. Fireworks saves images as PNGs by default.
