While testing I’ve noticed the header image is that header images uploaded by users are not considered as used image.
It is used, but not in the content.
API doesn’t have any endpoint to check what is the current header image.
...
This can lead to removal of some cool headers
What can be done?
Wait for the Confluence API to include the header attachment
If it is already possible and app didn’t make any announcements, pelase contact support with info how this can be done
New feature → Ability to tag header image
Filtering by tags is something that I’m planning to do: https://trello.com/c/soLvM8Dv/5-filter-by-label
