Hello,

I am currently using Piwigo as a gallery for (among other things) my Final Fantasy screenshots, taken in PNG format. However, they end up uploaded without the correct creation date set even though I am reasonably certain that I have it set correctly with exiftool.

Having said that, setting the metadata ahead of upload every single time is a major pain, and I'd much rather have the information retrieved from filenames if appropriate. Is there a plugin to do so?

Hi :-)

Have you read this doc page -> https://piwigo.org/doc/doku.php?id=user … amp;s=exif

I have! It was most unhelpful. I have learned that PNG files do not store the metadata in the same way JPEGs do, but no matter how I tried to populate my own PNG files nothing seemed to stick upon upload.

Could you provide a link to a sample image?

Sure! Here is a picture that should have had its metadata set with exiftool, but as far as I can tell none of it sticks and/or Piwigo never reads the creation date correctly.

Seems Piwigo can't read any EXIF/IPTC data from PNG. The PHP read_exif_data() function apparently also can't. After only 4 years of EXIF in PNG (eXIf chunk standardization) that standard may be too new.. *cough*

As a workaround you could convert to JPEG before uploading, e.g. using ImageMagick
convert file.png file.jpg

I could, yes, but that's still adding extra steps to my original issue of "I would like to pull the date from filename if not present in metadata"

erAck · 2022-01-10 00:35:37

Well, pulling dates from file names is not possible (unless you implement it), so ...

Thus my initial question: is there anything that has this particular feature? A plugin, for example? I'll take that as a no.
