Transform Image and keep metadata
Hi, I've just signed up to Cloudinary as I need to deliver metadata for copyright purposes within the image when delivering the images through my site. Using a sample image I have added the keep_attribution and keep_iptc as per:
https://res.cloudinary.com/dnzzmmvxk/image/upload/fl_keep_attribution.keep_iptc/v1632142127/samples/bike.jpg
but yet the metadata does not appear to exist. The original metadata contains all these values:
Can anyone point me in the right direction as to what I am doing wrong please.
Many thanks
Guy

Hi Guy,
The most likely reason that the keep_iptc flag won't preserve metadata on the derived version of an asset is if our automatic quality transformation was used either in the URL directly, or as your account's default quality setting ("upload" tab of the account settings).
There's a note about this limitation in the documentation, and it's because the different tools and systems used for automatic quality may modify the metadata in unexpected ways, requiring it to be cleared: https://cloudinary.com/documentation/transformation_reference#fl_keep_iptcThe keep_attribution flag should work in that case, however, so if you're seeing copyright-related fields (in particular, "artist, caption, creator, copyright, copyrightNotice, artworkCopyrightNotice, creditline") are missing, but were present on the original, please open a support request with an example and we can check it for you
Regards,
