I recently was given an old mac Mini from a friend, but iPhoto is not installed, and it is too old a version to support a current update - what can I do?

I was recently given a Mac Mini from a friend. It is an old version (model A1176) and cannot support a current version of iPhoto from the app store. It originally came with iLife, but was apparently wiped when they cleaned the hard drive to give it to me, and they cannot find the CD to reload it. I can no longer find iLife '11 in the app store. Is there anything I can do to be able to store photos from my iPhone onto the computer?
