Moin moin!
There is a esay way to solute the problem. Change the presets in the admin section. In german it called…
Einstellungen -> Verschiedenes:
‘Uploads in folgendem Ordner speichern’ [../mediathek]
‘Kompletter Pfad zu den Dateien’ [https://www.realtimespacelab.com/mediathek]
So if you use ‘/wordpress’ as a subdir it will be possible to use ‘/mediathek’ as an Imagefolder.
