I don't think that is true - I'm pretty sure GIMP performs most tasks
internally or through plug-ins.

GIMP can be used for batch processing as described here:
http://www.gimp.org/tutorials/Basic_Batch/

ImageMagick is a separate command-line image processing tool and also
very useful in batch processing.  There are tons of howtos out there
on using ImageMagick.  Once I even printed out the output of 'man
convert'.  Be sure you have plenty of toner/paper before you try that
though :)
