How to download iPhoto for mac os 10.7. (Mac completely restored 2wks ago

I had my macbook completely restored about two weeks ago and unfortunately lost iPhoto along with it. I have a mac os 10.7. Is there any way to download an iPhoto that would work with this older system? Everything I have been finding is for 10..8 or higher. If there is no older iPhoto - is there another application that I can use to house my photos and have the editing capability?

Thank-you!
