for f in `ls`
do
  for i in `file $f | cut -f 2 -d ',' | cut -f 2,4 -d ' '` # hsize vsize
  do
    if [[ $i < 100 ]]
    then
      rm -rf $f # try echo $i for the dry run
    fi
  done
done

If you use file on an image, it gives you that image's dimensions:

$ file yourimage.png
your_directory/yourimage.png    PNG image data, 512 x 512, 8-bit/color RGB, non-interlaced

Just parse out the numeric value and determine how you want to keep or delete the image based on the value.
