PmWiki doesn't do any image orientation/rotation at all. What you see is
done by the browser, only.
Browsers do not always behave identically, so I recommend using at least
`exiftran -a` on the uploaded (or soon to be uploaded) pictures.
Note that your desktop picture viewer (gPicView, gThumb, GIMP,
kolourpaint among others) and possibly your file manager may rotate the
pictures while viewing, so you wouldn't know if they are actually saved
upright or only have an orientation tag.
In the case of your 2 pictures, only GIMP detects the orientation tag
and asks if I want to rotate it or keep the orientation; gPicView,
gThumb and kolourpaint, and my file manager PCManFM all show one of the
pictures upright, the other rotated left, like Firefox.

BTW the PmWiki gallery addons "Mini" and "Thumblist" do not use
orientation tags either.

notice the first and last image, they looks the same, but if you clic
on them, the first displays vertically, the last horizontally.
the code is the same for the two images (very basic)
%newwin width=200%[[Attach:web_P1020187.jpg|Attach:web_P1020187.jpg]]%%
but the first image have the orientation tag of 8 when the last have 1
(= normal, forced by exiftools)
so looks some code in pmwiki follow the orientation tag, not the other
