Isolate one image on a .jpg and send it as email attachment
When my mother died, our family had her photo albums' pages digitized as .jpgs. I was told at the time that isolating any of the photos on a page was easy; otherwise, we would have had to have each photo digitized separately, an extraordinary expense for at least a thousand photos. I thought I knew how to do that (isolate an individual photo), but I haven't been able to find any instructions; in fact, there seem to be very few articles about .jpgs (or I haven't found them).
The .jpgs are on a flash drive, not in Photos on my MacBook Pro (early 2015), running Sierra. Is it necessary to get them there before I try to isolate any part of a .jpg page? And if I do that, will I be able to isolate individual photos on one of those pages and then attach it to an email message?
I'm sorry, but I am so ignorant about all this. I'm sure that the digitizers were very good, but I hope that they were right when they said that we'd be able to make separate images (also .jpg?) from the photos on the pages.
Can someone send me very clear instructions about this? I've managed to find out how to get the files into Photos from the flash drive but don't know 1) whether that is what I need to do and then how to isolate individual photos from the pages and then make the ones I choose into .jpg files.
Thank you so much. Apologies again.
