+# How to run:
+#	start gimp
+#	click (maybe twice) at the "Batch mode" menu entry (next to "Help")
+#	choose a file, that contains a list of absolute filenames of pictures (one per line)
+#
+# The resulting pictures are placed besides the originals with the given prefix (default: "converted_").
+#
+# Adapt the settings below to your needs!
