BIMP predecessor from 2008 (but still useful, e.g. read on Gimp-Forum.net here).
DBP (David's Batch Processor) is a simple batch processing plugin for the Gimp - it allows the user to automatically perform operations (such as resize) on a collection of image files.
Its main advantage is that the user does not have to learn a scripting language. Like the Gimp itself, DBP relies on a graphical interface.
The user creates a list of images, and sets up the processing required for each image. The results of the current settings can be displayed.
Once the required sequence of operations has been set up, DBP performs the same processing on each image in turn. The images can be colour corrected, resized, cropped, and sharpened, then renamed and saved to a different file in a specified image format.
All the steps (except loading and saving the image!) are optional; so the simplest use of DBP is just to convert a number of image files from one format to another.
Note that DBP is intended for RGB, not indexed images. Trying to process an indexed image will probably just cause an error, and DBP will halt.
Also, DBP will not overwrite the original image (in fact, it should not overwrite any file) - images must at least be either renamed (possibly by changing the image format) or moved to a different directory.
