from urbandictionary.com:

Ping (n.)

Brief email or other message, essentially just to ask

"are you still out there?"

PNG (n.)

Acronym for Portable Network Graphics, which is a bitmap image format that uses lossless data compression.

PNG was created in an effort to improve upon and replace the more common, as of its creation, GIF format. PNG, or "pings", have the advantage of not requiring a patent license, being platform independent, and being able to display more than 256 colors.  

One of the biggest detractors is that the PNG format does not natively support animation all though efforts are underway such as APNG and MPG.

All though PNG is officially pronounced as "ping", the acronym form, "pee-en-gee", is often used to avoid confusion with the ping networking tool/command.

Here at the newspaper, we are able to utilize images in PNG, JPG, GIF, TIF, and other formats.

Ping (n.)

"Packet Inter-Networking Groper." PING Can be used as a command in MS-DOS. Early computer programmers used this acronym because of it's similarities to a SONAR ping. A computer ping will send a packet of data from one computer to another to measure the time it takes for information to be sent and received. Pinging a computer can also help diagnose problems within networked computer systems.
