That means I am right with my assumption that I need 2 files, since download and upload are not the same files.
BTW: Regarding the not working option. My colleague changed something and I can give you “fresh logs”.
Have a look at sw-media.image-generator.image_root_folder_name. The content was Root and should be changed to Root folder. I tested it on friday, to approve the old one and remove the new one, since I knew our schedulded uploads will change it again. And there you can see it. It adds Root folder as a second translation, but the original one is still approved.
Please tell me me when I can change it and you have seen the logs you wanted to see.
