You get a zip file of the photos for the month you are looking at on the screen. Haven't investigated beyond that at this time. As in, what size are the images, etc.
@kjarn@30pics4jackiesdiamond Go to your Latest photo and click on 'view this month' above the thumbnails. You'll see the download button at the top right in the bar where your name appears.
16mb for my file of byrdlip_2019_2020-03.zip
Thank you for point that out.
It looks like the naming is "username"_"album"_"year-month" album and yr/month seem out of sync as I was browsing thru, it seems.
