Implementing a PNG loader is quite difficult, I recommend looking into libpng if you want to use it in your applications:

Depending upon the API you are targetting, PNG loading may already be built in. Both DirectX and GDI+ have built-in support for PNG loading. With other APIs, your mileage may vary, but you probably want to check before doing a lot of work integrating libpng or such into your game/engine.

A lot of work ? You mean the 40 lines of code needed to include libpng into a texture or image loader ? The 2 minutes it takes to essentially copy and paste the example code that comes with libpng ?

Use libpng, it''s a very good library. Very easy and simple to use, platform independent, and high standard conformance.
I also recommend using png, but I use SDL_image to load it. It works nicely, but may only make sense if you are already using SDL.

My 3D Pirate Game is in need of a better name, want to help?
