Some images uploaded through Image Picker have wrong orientation. So vertical image become horizontal oriented (rotated 90 degrees).
I had this problem too, but in webflow. Weird! I think back then I sorted that it was because I cropped the image and somehow that caused this issue. Did you crop these photos or are they being uploaded in their first form?
Not cropped. Edited through iOS Photo.
Can confirm this issue.
If you upload a different size, anything but the original photo, it rotates the photo by 90 degrees.
