Phatch

If you've ever tried to find the batch processing features in The Gimp, you'll probably have worked out that they don't exist. Phatch might be of use for you if you want to edit more than one image at a time. It's a photo batch processing application that could save you quite a bit of time. It includes:

• resize
• rotate
• rounded corners
• shadows
• watermark
• drag & drop droplet
• colour mode
• dpi change
• rename
