locked photos - how find, unlock
Hello,
Using iPhoto '11 (9.2.1) under Lion 10.7.2.
Am encountering problems with "locked" jpg files -- for example, I have one event that shows 90 images and I go to merge another that has 12 images -- I would expect to have 102 in the merged event, but end up with 300 -- the excessive 198 have only an icon, not a thumbnail -- I can click on them to display, and see them, but they're older images I intended be trashed. I have found older discussions pre-Lion pre-iPhoto 11 but thought I would repost the questions:
How do I find all these locked photos?
How do I "unlock" them? Am really unclear about this; please be explicit.
How do I permanently get rid of them, forever gone, not to come back and haunt me from one trash or the other? (OK, I'm a little frustrated; bear with, please...)
Thanks, in advance
PS -- additional variables include using 5 different Sony cameras, all of which start numbering images from scratch with DSC00001 (grrr....), Also having Aperture installed (no similar problems there)...
