<p>PNG absolutely supports metadata. It is not defined/standardized as much as jpg, but is supported, and digikam writes to it all the same info, and I find most programs I have tried also read it fine. GIMP unfortunately does not yet retain png metadata after editing, so must copy using exiv2 or exiftool, but there are plans to fix that eventually, I believe. </p>
