If you click to an empty Album, Plogger nicely tells you "Sadly, there are no pictures yet. Why don't you upload some?" And if you click on "upload same" it brings you to the upload image page. Sadly, the perviously visited empty Album is NOT be selected by default.
I went ahead and added the code fix for this in revision #611. It should be available in the next release (or you can download from SVN or manually edit plog-admin-functions with the linked changes).
