Re: jpg quality question with imagemagick and Gimp

The default is to estimate the image quality or use 92 if it cannot 
make a good estimate. Therefore, below, you have estimated quality in 
the first and used quality=100 in the second.

Also you will be more efficient if you use -strip right after the 
input, so those things don't get passed to the resized image. 
Moreover, you will be even more efficient if you use -thumbnail 
rather than -strip and -resize.
