Thanks Old. I found that Gallery you spoke of but was looking for the "old" gallery. I had thousands of pics on the old site that go back almost 20 yrs...if those are gone I'm going to be REALLY pissed.Scott, at the top right there are 3 vertically aligned dots. Click them, select gallery, and a box opens on the left of screen. The lowest selection takes you to your gallery pics. Don't expect all your old pics to still be there, though. Apparently, they didn't all migrate from the old database. All the pics/videos I uploaded to a Delta Lunch Bunch Hookie Day thread in 2017 are MIA as are dozens of older pics. Only 2 of mine made it through the software change.
I have no idea how to upload into the gallery as I haven't tried.
EDIT: once you are in "Gallery", the "Add media" button appears on the upper right.
