Thanks for posting this. I was curious too, but what is that drop down menu on the bottom left below your iPhone name? Are you suppose to select: image capture, iPhoto, preview, or auto importer ? Didn't want to mess things up before I deleted. What do these choices do? Thanks.photos have been imported already long time ago, i chose not to delete them at that time
but now i want to delete them all
but yo, its ok, i found it
open program IMAGE CAPTURE
select all control A
click delete, red button. BAM!!!!
