Whenever I open an email, the images from the sender upload to my iPhoto events/library. How can I filter the iPhoto events to those I manually designate to go to my iPhoto events- such as camera or files that I can send directly to that folder.

The extra images from client signatures, applications icons and even iTunes album or movie art keeps appearing in my iPhoto events and it clutters all the sorting that the face recognition, place and date albums I am managing.

Thanks for your help!
