Unrotated images in browsers

The following images were captured in fall 2020 after running thumbspage (version 1.6, where auto-rotation was added) with rotation disabled in configs, and then manually propagating source-image orientation tags to the first two (leftmost) thumbnails. Because sources already have valid orientation tags, if a browser supports rotation itself, only the third (rightmost) thumbnail will render askew (landscape); other thumbs and all sources should be right-side up (portrait).

Leading "d-" and "m-" in titles here mean desktop and mobile, respectively, and a "NO" means rotates didn't happen. thumbspage considered relying on browsers to reorient images, but abandoned the idea when these findings showed that support in browsers is slowly arriving but not universal, and even in some best cases won't be available in browser releases just one or two years old.

See the 2.0 note for more on the abandoned alternative, and this gallery's parent for results of thumbspage's own and universally portable image rotations. While they last, you can also access the images used to generate this page's results online as both gallery and zipfile; these aren't bundled with thumbspage's package because they're intentionally unshrunk and would add 18M, but such is the convolution of today's browsers that developers must also be empiricists.
