Phatch is a simple to use cross-platform GUI photo batch processor which handles all popular image formats and can duplicate (sub) folder hierarchies.
Phatch can batch resize, rotate, rename, apply watermarks, rounded corners, shadows, ... and more in minutes instead of hours or days if you do it manually.
Phatch will also support a console version in the future to batch photos on webservers. An Ubuntu deb installer is also available for download.
