Q: How do I get my albums from i photo into photo

Problem solved thanks to visit to Apple store.  By the time I went into the Apple Store I thought I knew what happened, but couldn't re import. When I imported my photos to photos I had two files to choose from and evidently picked the wrong one.  Going into finder I could see both files, but they were'nt highlighted so I couldn't import the other file.  The guy at the Apple Store suggested to hit the option and photo on the dock at the same time to see if I could not bring up the other file.  If that didn't work he said to go to finder and hold control while clicking on picture.  The last method is what ended up working and then I was able to import the other file. Bingo, the side bar now shows events from I Photo and the Albums.
