Can anyone help please ? I imported all my photos six months ago from my PC when I bought an iMac and they all went into iPhoto. On my PC there were 22gb of photos. Now I find that my iPhoto library is over 100gb in size. I have not put more than 50 photos on since the transfer. I have read all that I can on iPhoto but I do find it the least intuitive piece of Apple software. How can I sort this out before the whole thing becomes unmanageable ? Disc space is not a problem but it will become so it the iPhoto library continues increasing. Thanks.
