To present pictures in my photoblog I sometimes just cut a certain section out of the original picture. In detail it means that I create a completely new picture with a different size using The GIMP. The bad thing: EXIF data isn't copied doing that kind of manipulation (of course!).
Since I'm really interested in the camera settings people used to take certain pictures I definetly wanna have a look at the EXIF data. To transfer this data from the original picture to the newly created one GIMP doesn't offer the needed functionality. But there's hope - it's called jhead, an EXIF jpeg header manipulation tool which is available for all popular platforms like Linux, FreeBSD, OS X and Windows. The debian repositories offer a package as well.
To transfer the EXIF data this simple command line does the job:
There's even a special command for batch operations. This would be
where the parameter &i substitutes the original filename for this name.
Of course this operation invalidates the EXIF size values of the picture but that's not the point in most cases anyway.
