Okay. This is the weirdest thing and it happens every time I set up a new mac. It started with my Macbook Pro. Brand new computer...I turn it on, set up some stuff (ichat, mail, itunes, etc) and BAM there are a whole bunch (close to 500) pictures of mine that have been on my iMac. These weren't backed up anywhere that I know of (I don't have an external harddrive so I know it's not on Time Machine or anything.) I didn't think much of it then. I actually thought it was good so I didn't have to transfer them over. Then I got the 11in Macbook Air a week or so ago. SAME THING HAPPENED. 500 pictures just show up in my "All Images." I returned the 11in and got the 13in and I just noticed now.. ALL the pictures are there. Where are they coming from? I really, really don't want them. I keep deleting them everytime I get a new computer and it's getting annoying.
