Wolfgang,
I agree that the patch is likely not in FWTools because FWTools uses
a stock external libjpeg instead of the adjusted GDAL libjpeg.
I'm not exactly clear what the temp file is for. I have the vague
impression it is only needed with progressive jpegs, but I could be wrong.
I don't know for sure where it is created.
Best regards,
