nconvert -overwrite -buildexifthumb problem

Hi,

I wanted to recreate exif thumbnails of a bunch of jpeg but I noticed that nconvert also recompress the jpeg itself (with higher compression ratio) ... this is bad, is there a way to avoid this default way of work ? nconvert should not touch original jpeg image/compression if not explicitly requested.

Regards.
