Modifying photos

[psalms144.1]

Hi, y'all. Trying to post some photos, but even though they're showing as right side-up on my computer, when I preview post here, some of them are upside down, or rotated 90 degrees. Is there any way to change that in the posting process? Any other advice gratefully accepted.

Copy the photo, paste it to a new file, save it with the correct orientation. Should work.

Do NOT just do a save-as. Save-as will retain the original meta-data.

Holy crap, we've spent a lot of time bitching about photo orientation.
