When I embed a JPG image Inkscape does not respect the Orientation tag in the EXIF data. This has not been a problem previously, because I would just rotate the images in Inkscape and proceed. However, I now need to display these SVGs in a web browser (which does respect the EXIF Orientation tag), and thus I get different results.
Here is a screenshot showing the same SVG content in Inkscape and in Chrome.
Here is the SVG content, including the embedded image (which has an EXIF Orientation of 6).
Beyond the Basics EXIF Orientation is not respected for embedded images
