#    @num_colors            Number of colors to use for output images. The smaller the number, the smaller the file size, but this can also decrease image quality.

#                           iPad should support jpg, gif, and tiff.
#                           If your source images are not one of one of these supported types, then you will have to force the image type.

#                           Note that if you set this value to original, then the converted images will be of the same type as the original images.
