Can I auto rotate based on EXIF information?

Hi all,

I have a gallery3 install running, and have used the "server add" module extensively to add a large number of pictures.
A lot of the images however are tilted 90 degrees, and not automatically positioned correctly.
Is there any way to losslessly rotate them using the EXIF information? Ideally I would like to do this as a batch processing option under maintenanc, or something similar.
The regular rotate functionality ignores EXIF and will destroy the graphics quality in the process.

Thanks for your help, and an awesome product.
