FYI,
For anyone interested in Pattypan for bulk uploading images to Commons, there is a new version that came out 2 weeks ago for Microsoft Windows that is very easy to run. It is a single download and does not require fumbling for Java or special libraries.

In case anyone finds it useful, as the Linux and Mac versions are not nearly as easy to run.
