Just thought of sharing PhotoInfo 2.0.1, it's a simple app that you can use to change the date/time embedded in the EXIF data of your digital camera photos, in case you didn't set the time correctly on the camera.. I found it useful, coz i accidentally changed the camera date without realizing it and the arrangement in iPhoto's library went crazy...

Don't know whether this has been posted, but Skitch is a great new application, it'll change the way you screen-cap forever! Simple, all in one solution! Icon is a little girl-ish, but the fact that it's easy to use makes up for it
