Exif Jpeg header manipulation tool

Exif Jpeg header manipulation tool

Pre-built OS-X Intel executable jhead (61 k)
Pre-built OS-X PPC executable jhead (67 k)

The program also has a lot of other command line options for manipulating Exif files, such as options to manipulate the date in the header, renaming image files, or coordinating running Jpegtran and Mogrify to manipulate whole directory trees of images.

Here's the program files. Just right click and save as. The source archives should end in .tar.gz (as in jhead-2.7.tar.gz). Windows browsers have the annoying habit of renaming files on saving, so you may have to rename the file back to what is shown for programs to recognize them properly. You can use WinZip to open .tar.gz files.

For novice Linux/Unix/OS-X users: Don't forget to set the executable bit after downloading the pre-built executables. Type "chmod +x jhead" at a shell window after downloading it to do this. You don't have to do this if you use one of the RPM packages.

I don't at this point have an OS-X machine to build the binary on, nor do I have a RedHat system to build the RPM for that anymore. Until somebody builds it for me for those platforms, just use the previous release - it works just fine.
