I noted the same problem last week and decovered the imagemagick
port does not support the jpeg codec by default any more..  To
fix this you need to rebuild, doing something like:

   portupgrade -f -m '-DWITH_JPEG' ImageMagick-5.5.6_1

Other formats, like png, need to be added in the same way.  A
real annoyance, IMO.

HTH,
