Description Mathieu Saby 2024-05-12 17:07:24 UTC 
I don't think there is currently an API route for getting a local cover image (stored by Koha) from the biblionumber of the record

It could be useful
Comment 1 Magnus Enger 2024-05-14 07:20:44 UTC 
You can do requests like these: 

https://<opac>/cgi-bin/koha/opac-image.pl?thumbnail=1&biblionumber=68225
https://<opac>/cgi-bin/koha/opac-image.pl?biblionumber=68225

...and get the image back. What would the API return other than the image itself?

In my opinion there is still something missing though.
There is no way to know if a record actually have a local cover image or not.

If you use a generated link with the biblionumber in the hope that all your catalog will have cover image then many records will be missing a cover (unless you provide a local cover image to all your records).

It would be great to export the local cover image to a marc field only if it exists.
we could then check the presence of this field (unimarc 856u for example) to generate a cover image link, or not.

oh I did not know the URL https://<opac>/cgi-bin/koha/opac-image.pl?biblionumber=68225
It suits my needs
Comment 5 Mathieu Saby 2024-05-14 09:02:35 UTC 
but I agree with Arthur's comment, we should have a way to check if a record has a (or several) local cover

But you can not use 856u in unimarc for that, this field must be reserved for the link to the online ressource itself (see https://www.transition-bibliographique.fr/wp-content/uploads/2018/07/B856-6-2010.pdf , in french). I think marc21 is less strict.
