is there a way to rename files during the upload progress within the Wordpress 3.0 backend? I would like to have a consistent naming of files, especially for im
You can't autorename file with the media library function. I would recommend to rename files before you upload them. Even after uploading a file you can't rename it throug WordPress but only through FTP.
The only way to do that would be a plugin that hooks itself into the media library upload process. But it would really be easier to do that before uploading files.
