It makes use of libjpeg features of being able to load an image by only decoding the DCT coefficients needed to reconstruct an image of the size desired. This gives a massive speedup. If you do not try and access the pixels in a format other than YUV (or GRAY8 if the source is grascale) then it also avoids colorspace conversions as well.
