I need to know what program can open PNT files?

I have an image from a ping platter coming from our vendor and I can't open it with anything I have.

Any ideas?

Do you mean this? PingPlotter
There's freeware at the bottom of this page: Ping Plotter Download

I did mean PNG and I did get Ping Plotter. Sorry about the mixup.
