Either

1. Follow the link to the Mac OS X binaries on that page you quoted.
2. Install via macports or fink.
3. Download the source code, extract it, follow the instructions in the README file (basically configure, make, then sudo make install).

looks like .... not an easy task for non programmer.

Go with nr. 3 then, the readme will give you the steps which are literally 4.

http://mxcl.github.com/homebrew/ is an alternative too.

But why do you need libpng if you've never installed anything via terminal nor are you a programmer?

was trying to view iphone png files.

in windows, i use i-funbox, simply copying over to explorer it will auto convert the png.
but i couldn't find a solution in mac os. iclarified has the solution, but the libpng was the old version

libpng is not going to do what you think it does. It is a library for programmers to use to be able to manipulate (or create, or decode for display) png images. However, the important point you are missing is that png is a normal image type (just like gif or jpeg). Preview (or Safari, or Pages, or QuickTime, or any other program that can view images) will happily display them for you.

No iPhone pngs are not standard PNGs.

The PNG images found on the iPhone include extra data before the PNG header and compressed image data without the traditional headers and footers. Also, the red blue pixels are flipped (BGRA instead of RGBA)

He just needs to compile it and then follow that guide.
