I upgraded to OSX and lost all my photos from Ilife acan I get them back

Are you sure, you are viewing the correct iPhoto library? iPhoto may have created a new Library.

Hold down the alt/options key ⌥, while you double click iPhoto to launch it. Is there more than one Photo Library in the panel that opens? Then try the other libraries, if your photos are in there.

How did you upgrade your system? Did you do an erase and install? If so then you'll need to have made a backup copy of your library before the OS X upgrade in order to recover them.
