just installed Maverick on mac book pro....i believe no photo's on cloud like iPad...as i cannot change profile photo on user password page of preferrenceces

The options are more restricted in Mavericks:

• To change a profile picture in Contacts double-click the "edit" button on the Card.
• Now you should be able to use either the Faces or the Photo Stream from your iPhoto Library.
• 

Only, when I am testing, these options always are showing empty since Mavericks. Is that what you are seeing too? As a work-around, you can still drag and drop directly from the open iPhoto window directly to the contacts photo well on the card.
