Deleting photos from iPhone?

I put some photos into iPhoto and they transferred fine to my iPhone from iTunes. However, they look terrible when I try to bring them up... very fuzzy. How do I delete photos from the iPhone? TIA. I tried going back into iTunes but I don't see a delete or trashcan.

You can open Image Capture, click download some.... select the files and hit delete.

How do I open Image Capture? On the iPhone? In iPhoto? I'm a Newbie to both... Thanks.

Applications folder on your Mac. iPhone needs to be plugged in of course.

When I go there, there are no photos displayed. But they're on the iPhone and in iTunes photos.

there may be a better way, but the way i do it is
1. plug phone into mac
2. it automatically opens iPhoto
3. choose Import All
4. after import is done it asks if it should keep pics on phone, or delete from phone. choose delete

since you have already imported those pics, maybe take one more pic, import again, then choose delete.
