Most of the time I got issue with placed pictures that I have to take a lot of time to do it one by one, so I am looking for any action to peform in bulk as follow:
1. Select all pictures and change their 'Placment Options'
2. Replace all pictures with only one same picture
3. Cancel the repacement at once (if you select 100 pictures to relink, then you decide to cancel you'll have to press Esc 100 times too!)
I tried to create action for Placement Options too, but seems that the action cannot be recorded with such activity.
Are all these improved in CS6?
