Help a coder do some basic stuff with images

[Digital Jedi]

Does GimpShop have Actions and Batch processes? If so that would be the way to go about it. Actions record any steps you take while editing an image, and batch repeats a set of given Actions over multiple files. Toggling the Hue/Saturation is one way to get the color you want, and if it's possible in GimpShop, you can do a Color Overlay that's either set to Screen or adjust the Underlying Layer transparency of a given Layer. Like I said, I'm not sure what GimpShop does, but it does have some of those basic Photoshop features, maybe under different names.
