Hi Tony,
The map tips functionality for viewing photos is very difficult to style.
The ImportPhotos plugin has a nice interface for viewing your photos, you can also \
navigate between photos without having to move the cursor or click again. Navigation \
is chronological if you use the "Import Geotagged Photos" tool to "import" the \
photos. On my system the plugin imports them in a random order. Unfortunately the \
ImportPhotos plugin does not correct for the rotation, it seems to look only at the \
width and height. You may be able to correct this with image processing software \
before QGIS.

Hi,
A very newbie, Zurich/Win10.
Imported my photos into QGIS, used Display <img src="file:///[% photo %]" width="350" \
height="250"/>, toggled Map Notes, added single label, all worked fine. Except my \
photos are landscape but some are portrait. QGIS strips out most of the photo \
metadata but leaves Fields "photo" (combined path and filename) and "rotation" which \
is either 90 or 0 amongst others. NB: QGIS put Fields Long then Lat but other GPS \
software expect Lat then Lon. So as QGIS Expression has an IF THEN function is should \
be possible to check which "rotation" and change width and height accordingly. But I \
know QGIS syntax is very picky, so cannot stumble in the dark trying to guess how the \
expression should go. I guess something along the lines of:
<img src=if("rotate"=0, "file:///[% photo %]" width="350" height="250","file:///[% \
photo %]" width="250" height="350")/> Can anyone please tell me what I need to change \
please. Tony
