If I had the sd card with the 2016 phots I would just insert to the back of the imac next to the usb ports, but somehow I can't find the card.

I did a lot of search and found out my photos of 2016 went to the pages folder. Those were photos taken in Okinawa, and had several photos of my wife's mother that passed away last year. I restored my imac, and the seagate external hard drive only had data up to 2015. Before 2015 and after 2016, I have no problems as I have the sd cards, but the first problem is that I have to sent the photos from pages to photos on my ipad, than from ipad to imac. Tomorrow I am heading to the Apple store and seek some help.
Thanks everyone, I appreciated the help very much.

Thanks everyone for the response. I tried to use the icloud, and messed up every thing. I also lost all my photos in the ipad, and hopefully I have to find out where my sd card went.

I am trying to transfer photos from my ipad into my imac, but having difficulties. The imac recognizes the ipad, but the import doesn't work. Is there anyway that I can import from my ipad into the imac?
Thanks in advance.
