Original description:
In some cases i prefer PNGs over JPG, but it has one disadvantage, shotwell do not write any tags i it.
According to XMP specification:
“An XMP Packet is embedded in a PNG graphic file by adding a chunk of type iTXt. This
chunk is semantically equivalent to the tEXt and zTXt chunks, but the textual data is in the
UTF-8 encoding of the Unicode character set, instead of Latin-1.â€

- Priority set to High
Sounds reasonable. Upping ticket priority to high so that this could possibly make the next major release of Shotwell in March.
