Thumbs and automation.
Well no. You may be someone who read Jacob Nielsen's article on it and agrees that better thumbnails often come from cropping, moving the frame, and then shrinking, thean from mogrifying a batch to turn 3000 pixel images into 100px thumbs.
A thumb needs to do two of thd image things well, to grab the attention of the viewer, politely, and to convey the most important nature of the image.
Brains are still good at that.
