w3 png vs FireWorks png

Hello,

I have a litle doubt about FireWorks png and the w3 png.

How can two different kinds of files have the same name? Plus, can Gimp handle with FW png?

Thanks

PNG explicitly allows for application-specific custom data to be included in a file. If another application that doesn't understand those custom chunks loads the file, it will ignore them.

See: http://www.w3.org/TR/PNG/#14EditorsExt

AFAIK Gimp has no explicit support for Fireworks' custom data chunks, but it should load the regular image data just fine.
