Would it be possible/reasonable to extend image-upload (or serendipity_event_imageselectorplus?) to have an option like "create directory YYYY/MM/DD" if i upload a file? Could be a dropdown in settings with different kinds of directory-structure for example and a checkbox within upload-formular like "[x] create directory automatically".
At the moment it is a litte bit to complex to use this kind of structure and always have to create every single directory manually, if i upload an image for a posting.
