post tiger install

originally i did a combined upgrade from panther to tiger to keep my existing setup and programs such as ilife04. that worked fine.

recently i decided to for go the combined install and just install tiger.

I backed up my mail, itunes, iphoto library and installed tiger.

however my to my suprise tiger doesnt include ilife....? is there any way of installing ilife04 onto my tiger install? or do i need to delete the installation and do first install panther then upgrade to tiger (thus keeping ilife04?) or do apple want me to bu ilife05. i dont mine buying if i have to.. can i then just import my iphoto library back?
