I restart my mac coz i wanted to delete al the files on it and when I installing the new drive I chose macontish HD after istallation
I am still not quite sure what you did, but it does sound like you erased the drive ("coz i wanted to delete al the files on it") and reinstalled the system on your MacintoshHD.
Then there is no iPhoto installed. Do you have a backup?
If you bought iPhoto from the AppStore or it came preinstalled on your Mac you may find an iPhoto Installer at the App Store in your Purchases History (the fourth tab at the AppStore, not on the Updates or Featured tab). Install iPhoto from there.
