Describe the Bug
Similar to #1854 I believe that the orientation data for the image is not being respected when exporting to PDF. Since the fix was applied, my images show up in the correct orientation on Bookstack itself. But when I export, it reverts to the previous behaviour of ignoring the rotation
In bookstack
Export to PDF
Steps to Reproduce
Expected Behaviour

Thanks for reporting @TylerJMcLean,
Will be related to the upstream issue here: https://github.com/dompdf/dompdf/issues/2456
As a workaround, if needed, you could rotate the image via an image editing app (GIMP, Photopea etc...) so that the image itself is fully orientated (Rather than orientated via EXIF metadata).

Thanks @ssddanbrown for the quick response. I will do that until this is fixed.
As a side thought, it's pretty weird that some phones save it that way even when taken in portrait orientation.

Is there any solution to this?

@TylerJMcLean Here's the weird thing: This happens even when the phone that took the picture doesn't put an EXIF tag that causes the image to be rotated. I've got a Samsung Galaxy S23 which doesn't do that (I checked with exiftools), but whenever I take a picture with my phone and add it to a wiki page it's always rotated. Most of the time it's only slightly amusing, but I'm uploading photographs of recipes I'm archiving and it's a huge pain in the butt when it comes to transcribing the text.

Just to throw out some other options to work around this:

If you've been seeing rotated images outside of just PDF exports (in gallery and in content) then this may have been due to some changes in v24.05 which have been addressed in https://github.com/BookStackApp/BookStack/issues/5462.
