Greetings...I am trying to export a group of photos from iPhoto '08 and want to custom size them to 1920x1200. How do I accomplish that in iPhoto '08? I select: Size: Custom Max: Dimension of: ???? What am I supposed to put in the "of" field? It seems to only let you pick 1 dimension. Application help is useless. Any direction is appreciated.
