I have an iBook G4 with OS X 10.4.1. I use iPhoto 5.0.4 and lately I've had an issue that I can't resolve. I edit photos in iPhoto and then save them under Share>Export as JPGs with a new name in a new folder. The edits show in the iPhoto gallery, and when I pull the photos up in Preview. However, when I post photos to Facebook, the photos revert to the original, unedited version. This is very frustrating and I have absolutely no idea how to resolve. Help! Any ideas?
