Roll up, roll up! I've got a challenge.
You can optionally choose to compress pictures when saving in Office 2003 apps. This is automated in Office 2007. From what I can see, it is not possible to enable compression by default through group policy, or registry hacking. (If anybody knows different, please tell me!).
So, I had another idea - write a macro or find a program which can go through a directory of files, open each, and save them back with compression enabled.
But... I'm wondering if anybody has tried anything similar, basically, before I dive in.
