A file storage which uses a more sane rename method for existing files. Add `DEFAULT_FILE_STORAGE = 'site.storage.BetterNameFileSystemStorage'` (obviously changing `site.storage` to the module which you put this inside)
Upload an image with file-uploader from http://github.com/valums/file-uploader and save it to disk with the snippet and also to database if you want to
The title says it all — a subclass of FileSystemStorage which will overwrite files. Note that saves which fail part way though will leave the original file intact (see `test_upload_fails`). Based roughly on http://djangosnippets.org/snippets/2044/ .
