If you’re having trouble getting your pictures to orient correctly, make an account on Imgur.com. They’ve been around forever and I’ve been using it for at least 10 years. No spam emails. Free account. By design the site removes all EXIF data from the image. After uploading the images, save them directly from Imgur and they’ll upload exactly as you’re seeing them. You could also use an HTML [img]link[/img] code to link directly from the site.
I set all my albums as “hidden” and your photos will only be visible via a direct link.
I struggled with getting my pictures to upload correctly for quite a while this weekend, but I hope this helps others. It’s a reliable and easy way to solve the problem. I tried manually removing the EXIF data, saving the images myself, but nothing worked reliably until I tried this.
