Install ImageMagick and use convert foo.tiff bar.png or install pbmplus and 
use tifftopnm foo.tiff | pnmtopng > bar.png.

You'll need to add tiff to the filetypes the mf demuxer recognizes and 
connect a codec to it. Have a look at:

libmpdemux/mf.c
libmpdemux/demux_mf.c

and the image codecs:

libmpcodecs/vd_mpng.c
libmpcodecs/vd_mtga.c
etc...

This should get you started.

If your next post is a patch that adds tiff support, it is :-)
