问题
I installed the Magento2 open source sample data and everything works fine. When I switch to the luma theme in the admin backend I can see everything. But when I create a custom theme based on luma theme the data/images is not visible anymore. What am I doing wrong? Should it be marked somewhere?

Ok, I figured it out. I had to make two sql queries in the database because it was a problem with the widgets assigned to the old theme:
UPDATE layout_link SET theme_id = '[CUSTOM_THEME_ID]'
UPDATE widget_instance SET theme_id = '[CUSTOM_THEME_ID]'
