Larry,
I believe that setting works for new uploaded photos; I don't know it
applies to the photos transferred from the Yahoo Group.
Is anyone certain of the answer?
It does, and I am. I had to make use of that fact when transferring one of my own groups (which had about 4.7 GB of photos at Yahoo).
The transfer agent downloads the images at full resolution from Yahoo, and then applies the setting as it copies them into your Groups.io group.
Shal
