Can anyone please explain how this works?
She doesn't enter anything pertaining to the photo and it knows everything including the model of the camera.

Most cameras these days record all the information within the photo file. The programme which displayes the photo reads this info and displays it

if you open a picture that you have taken that is stored on your computer. Select properties and summary then click on the advanced button. That will show ALL the information that is stored about the picture

The info is added to the image file when the camera takes the pic. It isn't all that hard to extract that information. All photos include this info in the file. It's just a matter of knowing how to read it. Most image editing software will tell you at least part if not all of this info.

Thank you very much. I have learned something new!
I thought it was a very nice feature on their forum that all the photo info was added. I just couldn't figure out how it was doing it.

Thanks again.
