Rename files during upload within Wordpress backend

Question

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

Answer 1

I implemented the same thing, I wanted a more random filename, than the original, as the site I am using this for is for pics only and all files are in one directory.

i did the following

return md5($ip . uniqid(mt_rand(), true)) . $ext;
