I found this tip by accident and wanted to share it--hope you haven’t heard this before. One frustrating thing about the iPhone is photo management. Oh, sure, you get a chance to delete photos after importing them into iPhoto, but you only get that one chance, and it’s all or nothing. If you only want to delete some of the photos, you’ve got to do that manually on the phone--or so I thought.
Turns out there’s another way. Plug in your iPhone and open Preview, then select File > Import From [Your iPhone’s Name]. A window appears showing all the photos on your phone, and you can move them around, save them to disk, and delete them from the phone individually or in batches. Don’t ask me why this is in Preview and not iPhoto!
