I think that adding an FTP action would add great functionality to Phatch, and could be accomplished using python's ftplib. This would allow web gallery maintainers to use Phatch for processing images and uploading to their web galleries in one step. This would simplify maintaining galleries in CMSs like Drupal, Joomla, etc. and would allow web developers to give their clients a single cross platform program to maintain their galleries, with all batch processing an upload already configured in a handy action list.
I can add a blueprint for this if desired, at first glance it looks like it can be accomplished with ftplib. I am not suggesting that Phatch become yet another FTP client, but I think it could become the standard for maintaining image galleries, I would certainly add detailed instructions to the Drupal handbook on using this feature.
