In the "put up or shut up" department, I needed some procrastination time, was looking for an excuse to do something with LWP::UserAgent and XML::Simple, and thought that I might test my assertion that the published API would make it possible to accomplish your task. This works for logging in and requesting an upload ticket, and you will need to enter your particulars (email address and password, api key, and secret key). You will also need to develop the upload form and deal with the site's redirection scheme for a complete solution. I welcome any and all suggestions for improvements! #!/usr/bin/perl
