we would like to change the background image for the 10.0.3 release.
The picture must have the right creative commons license and should be committed to core in github.
I have opened a ticket in core here: https://github.com/owncloud/core/issues/28045
I'll make the start and recommend https://unsplash.com/search/cloud?photo=le60j2br1BI
I would like to gather your suggestions and will start a poll in this thread.
