How do I view all the photos in my iPhoto on my iPhone?
I have been trying to use iCloud to share the photos from iPhoto, but they do not show up on my iPhone.
Not sure that this will help but may depending on what version of OS X you have on your Mac. iCloud Photo Library does what you are asking about. It requires Yosemite 10.10.3 or later on your Mac and iOS 8.3 or later on your iPhone. It also requires that you use the new Photos app on your Mac rather than iPhoto.
