The name is tweetup but unfortunately I do not like/use twitter so it works on facebook.
$ sudo pip install tweetup
will do the job.
The command is:
$ tweetup -f <path_to_image> -d <descrption>
The above will upload a picture with the given description. You can upload a picture without a description too. For this do:
$ tweetup -f <path_to_image>
When you give the command for the very first time in your computer it will open your default browser window. It will ask you to login. Authorize the application and then set up the settings for this application and all done.
