Saving PNG problem

I found an archive that said you could use a DLL to save PNGs, but the links were dead. Does anyone know where these went to?

Try the 2nd link again.

Thanks very much!

Is it possible to save Alpha/Transparency information as well?

I discovered you can. The alpha information is stored first before the RGB.
