So there's zero backward-compatbility?

Seems unlikely.

Why? Because 1.6.7 can't handle older files?

The server is an EC2 box, using the Amazon version of RHEL, so yes it is
libpng 1.2.49. Still, seems a bit silly for the newest version that
Firefox dynamically uses to go "nope, not handling it, error".

| * File a bug report for libpng upstream.

This seems like the best course of action but, as I said origianlly, if
anyone has experience lodging bugs with these guys, I'd appreciate any
