Default Does the .png image format have a text metadata field?

Java Jive,

Paint will load and save PNG files, but know even less about them than
PSP, for example there is nothing under File, Properties to display any
image metadata.


Paint is an MS program. If the "file properties" dialog doesn't know about
PNG attributes, its very likely Paint won't either. :-)

And by the way: GDI+ (which contains the support for EXIF properties) does
not know how to write an EXIF property into a PNG image.

On the other hand, when using GDI+ to load a JPG image and saving it as a
PNG it does copy a JPG textrecord (id FFFE) into the PNG image as a "tEXt"
field, prepended a "Comment\0". They did not /fully/ throw their hats at
it.
