Hello, there are no meta data in the small pictures. Is it possible to copy the exif / meta data from the original image to all derivatives. Especially the copyright information. Many thanks for your help.

Is it normal, that in the derivates are not the metadata from the original image? Is it possible to copy the metadata from the original (in particular the copyright information), when the derivates are generated? It is important. I'm having some trouble with Adobe Stock images because the IPTC data was removed due to Piwigo resizing. Can anyone help me?

It's a config setting. To your local config add

Code:

// below which size (in pixels, ie width*height) do we remove metadata
// EXIF/IPTC... from derivative?
$conf['derivatives_strip_metadata_threshold'] = 256000;

with whatever value instead of the default 256000.

Thank you for your answer but anyway there is no metadata in any size.

Of course that setting comes into effect only when derivatives are created, not on the fly for already existing derivatives.

If you don't see metadata at all, not even for the original file, then maybe it's not extracted for some reason. Search the forum and/or use [extension by ddtddt] Read Metadata if the PHP builtin read_exif_data() is dysfunctional.
