Hi @Leon Wagschal,
SharePoint Online uses claims-based authentication. SharePoint Online does not have a claim called or aliased as Anyone or Anonymous Access or something similar. So, we cannot access a SharePoint page anonymously also SharePoint pages cannot be shared with "Anyone."
As an alternative, you can create a folder in a document library and upload photos to the folder. Folder is allowed to be shared with "Anyone".
