kfm picture preview file permissions
I noticed that after uploading, the pictures get 644 file permissions (owner can read & write, group, others can read only). But the thumbnails don't display in kfm file browser. Just empty frames. But it is not consistent (see screenshot22)
If at all this is a permission problem where are the settings?
Also, with this file permissions it is not possible to move files in another directory, because you are not allowed to delete. Where do I find these settings, PLEASE?
