Linux for Designers

Today the Libre Graphics Meeting 2008 starts in Warsow (Poland). I visited the website and looking through the schedule table. There i found Phatch a photo batch processor. Phatch is an standalone alternative to David's Batch Processor that works only inside of GIMP.
Ubuntu Linux ships with it, you just have to install the package "phatch". If you looking for a mass renaming utility take a look at pyRenamer.
