time machine lost my iphoto library

The hard disk of my imac has been changed.

All of the applications (Office,...), and all my documents were reloaded without any issue. For some reason, iphoto does not retrieve my pictures. I try with "cmd+alt+clic mouse", and everything the chap from the Macline store told to me but nothing works.

I try to update my iphoto but there for I need ilife and I don't wnat to buy it because I need it otherwise

Thanks for your help
