sips is a good tip, thanks! I often sort and process images with a macbook on my lap curled up on the sofa. Resizing locally makes the mac blazing hot with fans whining - not comfortable and kills the battery. Transfer speed is not too bad over 802.11AC. So I use it mainly as a method of moving cpu intensive work away from my lap. Also, I sometimes use parallel -S server,: ....... The semicolon adds the local machine to the list, it will saturate both the laptop and whatever it manages from the other computer. I have to admit I've never tested this scientifically, but it seems to be faster even with the overhead (gain of remote imagemagick seems to be more than cpu overhead of SSH file transfer).
