I Used to have iPhoto on my computer with tons of albums and old photos. Something happened to my computer and I ended up having to replace the Hard drive and reload OS X 10.7.5 off the internet and reboot so I am back up and running. I have all my files on a USB stick. However, It seems iPhoto is no longer available? I really need to access these photos that were in iPhoto, in addition to use some sort of photo software going forward. Thoughts suggestions?
