Images flipped 90 degrees

[tomleary]

Issue description

Images taken horizontally show up fine, but anything taken vertically is rendered horizontally.

The code is simply:

![Alt text](ghat3.jpg "Image caption")
![Alt text](ghat4.jpg "Image caption")

I feel like this can't be standard behavior, so maybe I accidentally changed a configuration file without realizing it. Otherwise, it might have to do with the way the theme tries to make all the images the same width.

Theme version

v2.6.1

Hugo version

hugo v0.112.1+extended

Which browser rendering engines are you seeing the problem on?

Chromium

Are you taking pictures with iPhone, which seems to have incorrectly rotated EXIF information?

[tomleary]

Those photos were taken with an Android, though I've had the same problem with iPhone photos, too. All the photos show up fine in every other image-viewing application. They also show up fine if I embed them with HTML instead of Markdown or the figure shortcode.

<img src="ghat3.jpg" />
<img src="ghat4.jpg" />

To assist (as a workaround and troubleshooting)...

I also have this issue with most (but not all) portrait images taken on my Android phone.
As a workaround, I am using an image editor on my PC to rotate the image 90 degrees, save, and then rotate back and save again... Now the image will appear in the correct orientation on the website.

I believe this indicates it is an EXIF issue. I am uncertain if the Android EXIF data needs to be fixed, or if there is another orientation indicator Huge can use.

I have seen this commented from time to time in the discussions and there's a lot on the Hugo Discourse about it too. There seems to be issues with how EXIF data is interpreted and that Hugo doesn't rotate the images to match the EXIF orientation. I might have to see if I can add this logic to the theme itself. See https://discourse.gohugo.io/t/image-exif-orientation/22902 for details.

I would find a way to opt-in to this behavior. You don't need to run every image on every site through this filter. Maybe use a site param to opt-in for the whole site, or a page param to opt-in for a particular page.
